Sometimes,acting is a family affair. And where these discussions often center around famous parents and their children, let’s not forget the phenomenon of famous siblings. In some childhoods, siblings fight for the limelight as they are determined to make their own path in life, without following in the footsteps of the other. At other times, some siblings embrace this connection and frequently hone their skills together.

Throughout the entire film industry, we see both kinds of dynamics. There are siblings likeShirley MacLaineandWarren Beattywho have never worked together. But then there are those likeMarlonandShawn Wayanswho regularly collaborate. It’s a matter of preference and fate, really. And yet, when siblings do appear in the same movie, sometimes these films strike hot. Indeed, these are the few that do.

10’I Am Sam' (2001)

Dakota Fanning and Elle Fanning

Abandoned in her youth, Lucy (Dakota Fanning) is raised by her father, Sam (Sean Penn), and his supportive group of friends. But upon reaching the age of seven, her intellect begins to surpass that of her father’s due to him being intellectually disabled. This warrants the concern of social workers, forcing Sam to fight for his daughter’s custody.

Where this movie technically features the appearance of both Fanning sisters, the two never actually shared the screen together. Indeed, in this emotional flick, Dakota and Elle play the same character, just at different ages. As the older version of Lucy, Dakota takes on a more leading role, which is met with much praise as she ends up earning a SAG nomination - the youngest person to ever do so, at only 7-years-old. Recently, the Fanning sisters were expected to star alongside each other in the World War II drama,The Nightingale; however, since the COVID-19 pandemic,this project has been kept in limbo.

9’Home Alone' (1990)

Macaulay Culkin and Kieran Culkin

Kevin McCallister (Macaulay Culkin), an eight-year-old troublemaker, is accidentally left at home whilst his family leaves for a holiday in France. Where he initially finds excitement in his predicament, those feelings sour very quickly when he finds two men attempting to rob his home.

With this movie propelling the older Culkin brother into international stardom, thanks toHome Alonebeing one ofthe most beloved Christmas moviesof all time, some may have forgotten that it also featured another famous Culkin. Indeed, Kevin’s little bed-wetting cousin, Fuller McCallister, was portrayed by 8-year-oldKieran Culkin. The two brothers only shared a few scenes together as Kieran’s role was relatively minor, but their interactions were fun nonetheless - especially since they got to continue their gags into the movie’s sequel. What’s even more amusing is how, at the time of filming, Kieranwas completely obliviousto the fact that Macaulay was playing the main character. How bizarre indeed.

8’You Are So Not Invited to My Bat Mitzvah' (2023)

Sunny and Sadie Sandler

Best-friends, Stacy (Sunny Sandler) and Lydia (Samantha Lorraine), have always dreamed of planning the greatest Bat Mitzvah there ever was. But these dreams quickly go awry as a boy in middle-school starts to stand between their friendship and their party planning.

Unlike the rest of the movies on this list,You Are So Not Invited to My Bat Mitzvahwas a complete family affair as it featured the entire Sandler family. And before anyone screams about nepotism, it should be noted that in this case, the real-life family dynamics helped enhance the setting of the story as it infused a sense of authenticity within the Friedman family. Stacy and her older sister, Ronnie, truly felt like siblings because they were played by real siblings. From the bickering to the bonding - all their interactions flowed quite naturally and convincingly.

7’Thor: Ragnarok' (2017)

Chris Hemsworth and Luke Hemsworth

Trapped on the planet of Sakkar, without the power of his mighty hammer, Thor (Chris Hemsworth) must find a way to escape from the other side of the universe so as to save his home planet from Hela (Cate Blanchett) - the Goddess of Death. But in order to do so, Thor must form an unconventional team.

PoorLiam Hemsworth. Despite being the first brotherto almost clinch the role, he is the only one that hasn’t yet played Thor. Indeed,Thor: Ragnarokprobably has the most comedic use of real-life siblings, asLuke Hemsworthessentially portrays an actor playing the role of Thor in a dramatic Asgardian play. Most of his time on-screen is dedicated to parodying his own brother’s performance. It’s all very meta. Perhaps, if there were to be a fifth Thor installment, maybe both Chris and Luke could share the screen together.

6’At Close Range' (1986)

Sean Penn and Christopher Penn

Where the core conflict stems between the sons and their father, Brad Jr. and Tommy share their own poignant moments of heartbreak and tragedy - much of which is seemingly compounded by the real brotherly bond between Sean and Christopher Penn.

This rabbit, named Frank, tells him that the world is going to end in around 28 days, leaving Donnie to spiral and commit a string of reckless crimes.

This is not the first time the Gyllenhaal siblings have been in the same movie. As kids, they both appeared inA Dangerous Woman, a film directed by their father,Stephen Gyllenhaal. However,Donnie Darkowas the first time they acted along-side each other, which proved to be a somewhat easy task since their characters were literal siblings. Once again, life reflected art as their real relationship added weight and authenticity to their character’s on-screen relationship, no matter how tumultuous it may have been. What’s funny is howMaggie Gyllenhaalwas initially apprehensive about joining the cast. Thankfully,Richard Kelly- the film’s director - didsome masterful convincing.

Luckily for Rosa, she has a theater manager with two wacky friends at Ricardo’s side as they try to unite the young lovers; albeit, in a rather comedically chaotic kind of way.

The Marx Brothershave cemented themselves in film history as one of the most famous vaudville acts and comedic influences of all time. And oftheir famed filmography,A Night at the Operais often considered their best work as it masterfully balances their skilled physical comedy with a compelling narrative. Indeed,Groucho,Chico, andHarponot only play a great team on-screen, but they excel as one off-screen as they seamlessly bounce off each other’s zingers and gags.

A Night at the Opera

In A Night at the Opera, Otis B. Driftwood, a crafty business manager, and his friends Fiorello and Tomasso help two opera singers, Rosa and Ricardo, achieve success while sabotaging their snobbish rivals.
