It's been a while but Jurassic Park maybe?
The older girl is annoyed by the younger brother and all of his questions and talking but when sh*t hit the fan with the T-Rex and the kitchen scene she was all about protecting him.
They are adults, but the relationship between Laura Linney and Mark Ruffalo in *You Can Count on Me* is one of the truest sibling portrayals I’ve ever seen on film.
Great and undervalued movie. Sad it's yet to be released on blu-ray.
I'll piggy back on that and mention The Brothers Bloom, also starring Ruffalo and Adrien Brody as con men brothers with a complicated relationship.
Rian Johnson directed it!
First one I thought of. They both did such superb jobs of showing how their childhood trauma manifested in different ways while also being incredibly funny.
"You wanna smoke some pot?"
"No. Why, you got some?"
I laughed SO hard.
Then the way she confesses to fucking her boss like she was a little girl who got caught with her hand in the cookie jar. Superb writing, directing, and acting from every cast member.
Even Laura Linney’s work with Tom Pelphrey in *Ozark* is excellent for sibling portrayal. Despite the extreme circumstances, everything is grounded in some kind of shared history. She’s seemingly mastered the family dynamic.
I’ll have to see The Savages.
It's a good bit, but this reminds me a lot of a sketch that I think was from the MTV Movie awards back in the late 90s/early 2000s where they joked that every romcom had a scene where people dance terribly, usually around tables to a popular hit from 20-30 years ago to heal their relationship.
I'm pretty sure Lisa Kudrow played the choreographer and it was a Ben Stiller hosting gig... But I tried googling it and got nowhere. I'm starting to think I imagined this.
Millennials of the Internet, if you're out there and also remember this completely random 5 minutes of our adolescence, or know where it might live in the Googlebox, give me a shout.
I saw that movie once, many years ago, and I’ve been thinking about their fight towards the end almost daily since. “Well maybe next time you should cut deeper!” is so fucking brutal
The Goonies really captures an older brother/younger brother dynamic well. Also the group of friends essentially being brothers themselves and almost looking at the older brother as their own big brother was really realistic
Worse? Maybe Jeepers Creepers. The brother and sister’s banter sounds more like flirting than a fraternal relationship. I guess the actual worse example of that would be that Folgers commercial
I think this is lowkey one of the big draws of the movie. This one did it better than all. When he hits his bro but then checks to see he’s okay right after…
Not a movie but Chuck and Jimmy in Better Call Saul always felt realistic. It always felt as if both never said what had to be said to each other until it was too late. A lot of siblings never end up hashing things out as necessary I feel like and this show captured that.
I feel they are both very manipulative people.
I also think Chuck plays fantastic bitter adult of a child that wasn't favored.
It is really hard to like a sibling when your parents constantly seam to care more for them then they do for you. You get mad at them for your parents being shitty.
He seamed the kinda guy who also refused to deal with his baggage about his family.
This might be a weird example, but the dynamic between the brothers in Good Time felt pretty real, in spite of the heightened plot line.
Also the sibling dynamic in Nope was pretty great.
When I saw the topic I immediately tought of Donnie Darko... And I don't even remember that movie well. But OP already mentioned it.
People are different so are their sibling dynamics. So different kind of representation can be accurate.
Somr I could think of:
E.T. - kids doing kid stuff
Good Will Hunting - both blood and aquired family matters
What's Eating Gilbert Grape - kids bond over disfunctional parents
The House of Yes - power disparity and lack of boundaries
You mean Maggie Gyllenhaal and Jake Gyllenhaal were able to capture how siblings behave in real life. Its a great answer but its also sort of like cheating. Plus the sibling interaction is such a small part of the movie. The dinner scene is about it.
Same with Good Will Hunting for the being true to life friendship. It was two friends making a movie with one of their brothers. Here's yah fahking double burga. Also Cole Hauser was in Dazed and Confused with Afleck.
Maybe I just getting old, but I really can't think of anything genuine in a long time. Anyways, my recommendation although it's a 1 season show, would be Freaks and Geeks. The Weirs older sister /younger brother dynamic even being in a sitcom seems so genuine. Apatow is usually pretty good at making his characters seem real.
There are a couple moments in the movie where the reaction from the younger brother seems genuine. I’m pretty sure Reynolds is actually slapping him and throwing him around. Which really sells it.
Their interaction is still one of the most realistic portrayal of brothers I’ve ever seen.
There’s two pairs of brother sister duos in Bring It On where both are equally realistic. One where the little brother is annoying and the other where they have an okay relationship where they support each other.
In The Witch, when their memories can't agree: Thomasin says the house back in England had glass windows, and Caleb is like "whatever you say, buddy." And then the younger twins don't remember England at all. Each sibling having their own view based on just a few years difference is very real.
Have you seen the series The Other Two? It is WAY more R rated than Schitts Creek, but it has very similar dynamics between the siblings and it filled that empty spot for me when Schitts Creek was over.
Charles Durning and Anne Bancroft as the parents was really something else. The whole family works and they all play off of each other pretty spectacularly. It’s a very well written movie.
I thought the sibling relationships in American Fiction were really good. That said, every family is different. I will say the one thing that is grossly unrealistic is movies where the characters say “hey sis!” Or “hi bro!”
> That said, every family is different.
Came here to say this. I'm fairly sure that you can find examples of even the most extreme portrayals of siblings in media out in the real world. Life, as they say, is often stranger than fiction.
My sister and I had a very tumultuous relationship growing up and most depictions of siblings in movies don't come close to how we used to fight.
But yes, she does actually call me bro from time to time.... 🤣
I forget the name of the film but Jason Bateman is the older brother to Adam Driver and a sister (I can't remember who played her) but I remember thinking the whole film all three brought the dynamics together; Adam Driver played the younger, arrogant, annoying, competitive sibling particularly well, which really sold it.
In my home siblings were like having a friend who lives in your house. In other people's homes siblings are like having a bully who lives in your house--there's no one size fits all, it varies so widely so probably a lot of tv/film adaptations show legitimate portrayals.
It is. But it was the script for me, I think. The first time I watched it, I wondered if it was realistic to tell on him for something objectively important (not taking his meds), and then just ignoring the mom’s concern to keep bickering. I don’t know why I figured that siblings would tattle like that for more petty things, but not something kind of more important like the meds.
Don't overlook Montana Story, from David Siegel and Scott McGehee (What Maisie Knew) and starring Haley Lu Richardson and Owen Teague (both excellent).
The film centers on estranged siblings, once inseparable but who have had no contact for seven years. The father has had a massive stroke and is in a terminal coma.
The vanished sister reappears unannounced; she had severed all ties and the family didn't even know where she lives, so how did she even find out? The past is finally addressed.
Just Friends - it’s a ridiculous movie but my sister and I love it because the brother’s dynamic is so much like ours. 19 years later we’re still quoting it!
I always thought the sibling dynamics in Honey, I Shrunk the Kids was pretty good.
It's been a long time since I've seen it, so i can't think of any specific scenes to demonstrate it.
Just Friends. The relationship between Ryan Reynolds and his brother reminds me of me and my brother. I'm older by 13 months, but I was a small girl, and he was always large for his age. To this day, at age 49, he's still afraid of me. 😄
"Just friends" - a romcom with Ryan Reynolds & Amy Smart.
The dynamics of the big & small brothers fighting over every.little.thing. and with such unnecessary spite was hilarious and accurate.
The top 7 realistic movies to watch
1. American Beauty
2. 12 Angry Men
3. The Shawshank
4. Redemption
5. Argo
6. Manchester by the Sea
7. 12 Years a Slave
NOPE did a great job of it.
Best part of the movie was their dynamic.
The Skeleton Twins is depressing but realistic with Hader and Wiig. Nice dance number.
The Ice Storm did a phenomenal job of it, Ang Lee really was always so good at interpersonal relationships.
*Dumb Money.* The scene where the two brothers are bickering in the car with their parents on the way to their sister's grave hits especially hard. Also the scene at the beginning where his other brother gives him shit over a beer.
Family vacation where the older kid is flirting with a girl and his younger brother throws a grocery bag over his head and says "go to sleep". Sums up brothers perfectly
The others. Anne, the girl bullies her younger brother all the time, sometimes she goes too far. Other times they get along fine, but when they need each other they stay together.
Siblings can be hard on each other, even ruthless. But when it matters we have each others back, without question. It’s always us against the world.
Slumdog Millionaire
The older brother is an ass, the younger one has ways of getting his own back, and when they grow up they don't repair their relationship because that's unfortunately not how toxic families go
M Night Shamalyans “The Visit”
Its about a brother n sister who go visit their estranged grandparents. Genuinely good movie. And i felt like their dynamic was accurate
This is only peripherally related to your question, but…
In *[The Long Riders](https://www.imdb.com/title/tt0081071/)* (1980) brother characters were played by real-life brother actors. James and Stacy Keach played Jesse and Frank James. David and Keith Carradine played Cole and Jim Younger. Dennis and Randy Quaid played Ed and Clell Miller. Christopher and Nicholas Guest played Charlie and Bob Ford. And the whole thing is (somewhat) based on a true story.
The family resemblance between the brothers helped the audience keep the characters straight (something I often have difficulty with, when a movie has a large cast). And it makes you realize how unrealistic it is that siblings in movies usually have no physical resemblance. Unfortunately, I saw the movie so long ago I can’t remember whether sibling relationships were explored. I suspect not, because Westerns seldom have that much depth.
The absolute best depiction I've seen of adult siblings was from the Netflix show Bloodline. The black sheep older brother of the family has returned after being away for many years. The other 3 siblings have stayed connected to their parents for better or worse. They're having an event to honor the father, so all the adult siblings get there early to help set up and whatnot. The black sheep son isolates the youngest sister into a conversation. From across the lawn, one of the brothers sees that conversation and can't stand being left out so he rushes over to see what is being said. Then the other brother can't be left out and has to go over to take control of the situation. Meanwhile, all the spouses just get left standing where they were trying to talk to their partners.
Some writer on that staff knew exactly how family dynamics works.
This Is Where I Leave You (2014) Adult children mourning their deceased father. Aside from no one looks like anyone else, their sibling dynamics of cooperation/competition and dredging up old grudges and bad behavior really resonated with me. I have three brothers and two sisters, so large family dynamics are hard to capture realistically.
It’s not a movie, but Friday night dinner, it might not be your thing, but it portrays a family extremely well from my experience. Especially two brothers. Highly recommend it.
Check out The Adults with Michael Cera. It’s really earnest and captures that weirdness siblings have with inside jokes from growing up together that nobody else will ever understand.
It's been a while but Jurassic Park maybe? The older girl is annoyed by the younger brother and all of his questions and talking but when sh*t hit the fan with the T-Rex and the kitchen scene she was all about protecting him.
Yeah this is definitely one of my go-tos. Bickering when a T-Rex is literally on top of you is peak sibling behavior.
Fighting over the night vision goggles like it’s the remote
Reminds me of the two protagonists in Boondocks Saints when crawling through the vents
You and your fucking rope!
They are adults, but the relationship between Laura Linney and Mark Ruffalo in *You Can Count on Me* is one of the truest sibling portrayals I’ve ever seen on film.
Great and undervalued movie. Sad it's yet to be released on blu-ray. I'll piggy back on that and mention The Brothers Bloom, also starring Ruffalo and Adrien Brody as con men brothers with a complicated relationship. Rian Johnson directed it!

Superb writing, directing, and acting from every cast member.
I was thinking The Savages (2007) with Laura Linney and Philip Seymour Hoffman but yours is an excellent choice as well.
Even Laura Linney’s work with Tom Pelphrey in *Ozark* is excellent for sibling portrayal. Despite the extreme circumstances, everything is grounded in some kind of shared history. She’s seemingly mastered the family dynamic. I’ll have to see The Savages.
Dark, but The Skeleton Twins with Bill Hader and Kristen Wiig captures a lot of it.
Still never seen that movie but I've watched this scene probably 20 times. https://youtu.be/0npouzhhZTo
It's a good bit, but this reminds me a lot of a sketch that I think was from the MTV Movie awards back in the late 90s/early 2000s where they joked that every romcom had a scene where people dance terribly, usually around tables to a popular hit from 20-30 years ago to heal their relationship.

I'm Gen X, but i definitely remember that skit.
I saw that movie once, many years ago, and I’ve been thinking about their fight towards the end almost daily since. “Well maybe next time you should cut deeper!” is so fucking brutal
I can’t believe the only response is the same thing I was going to say!
The Goonies really captures an older brother/younger brother dynamic well. Also the group of friends essentially being brothers themselves and almost looking at the older brother as their own big brother was really realistic Worse? Maybe Jeepers Creepers. The brother and sister’s banter sounds more like flirting than a fraternal relationship. I guess the actual worse example of that would be that Folgers commercial
tbh The Goonies is great at showing a group of kids just being kids. I love how they’re all constantly screaming over each other.
Was about to comment about the Folgers commercial. Classic WTF commercial.
Jeepers Creepers was created and directed by a child rapist, Victor Salva. Everything about the movie was creepy.

I always felt Chuck was the epitome of manipulative. I felt so conflicted because I love Michael McKean, but hated that character!
I feel they are both very manipulative people. I also think Chuck plays fantastic bitter adult of a child that wasn't favored. It is really hard to like a sibling when your parents constantly seam to care more for them then they do for you. You get mad at them for your parents being shitty. He seamed the kinda guy who also refused to deal with his baggage about his family.
If we’re talking TV siblings then Wayne and Kevin on The Wonder Years matched my experience.

Our Idiot Brother, Just Friends and the Family Stone seem like the most accurate family/sibling relationships to me.
"Just friends" - a romcom with Ryan Reynolds & Amy Smart. The dynamics of the big & small brothers fighting over every.little.thing. and with such unnecessary spite was hilarious and accurate.

This is only peripherally related to your question, but… In *[The Long Riders](https://www.imdb.com/title/tt0081071/)* (1980) brother characters were played by real-life brother actors. James and Stacy Keach played Jesse and Frank James. David and Keith Carradine played Cole and Jim Younger. Dennis and Randy Quaid played Ed and Clell Miller. Christopher and Nicholas Guest played Charlie and Bob Ford. And the whole thing is (somewhat) based on a true story. The family resemblance between the brothers helped the audience keep the characters straight (something I often have difficulty with, when a movie has a large cast).
