Actors that could easily play siblings.

Kevin Costner and Thomas Jane
Ed Harris and Viggo Mortensen

What are some others you thought looked similar?

 

Matthew McConnoughey and Woody Harrelson

 

Isn't this going to become another "lookalikes" thread?

To avoid that, it might be interesting to focus on male/female pairs who could be siblings.

 

The husband and the brother in Tully.

 

Jake Gyllenhaal and Maggie Gyllenhaal.

Hey, the thread didn't say they couldn't actually be siblings!

 

John Cena and Scarlett Johansson

 

I don't see it

 

Dwayne Johnson and Jason Momoa

 

Ryan Reynolds and Kate Beckinsale...

 

uh, I don't see that.

 

Bradley Steven Perry needs to appear on The Orville as Ed Mercer's kid brother. They even kinda act similar.

 

Rachael Taylor and Alice Eve

 

matt damon and jesse plemons

 

Shirley MacLaine and Warren Beatty. They don't look related, but I bet they could pull it off.

 

Bruce Willis and Peter Stormare.

 

Mark Strong and Stanley Tucci

 

Joel Grey played a sort-of-clone of Ron Rifkin in season 4 of “Alias” in part because people had said they resembled each other.

 

At one time Jim Carrey and Henry Rollins could have played brothers. About 15 years ago I wrote to Henry suggesting a script where he plays the straight-laced accountant brother and Carrey would play the Hell's Angel brother, i.e. both against character. The premise was they switch lives. Fish out of water, etc. Henry the up-tight accountant finds his inner badass and Carrey the hellraiser finds his inner suburban Dad-ness.

Jennifer Connelly and Daniel Day Lewis
