Ahhh, siblings. You can't live with them, you can't kill them. 

KIDDING! 

Today is National Siblings Day! The other day a year we pretend to like our built-in best friends because social media tells us to. (The first day is Christmas, because presents, obvs.)

In honor of National Siblings Day, which is probably a totally made up day created by someone attempting to bury the hatchet with a brother or sister by publicly professing that Imma let you finish by my sibling is the best sibling ever, our celebrity gossip editors thought it would be grand to take a look at some of our favorite star siblings:

From the fabulous to the feuding to the famewhores, Hollywood is rife with celebrity siblings. Now to decide if you and your siblings are more or less dysfunctional than they are.

Christopher Nolan is one of those directors who has his guys and sticks with them.

Michael Caine, Christian Bale, Cillian Murphy, Tom Hardy, Joseph Gordon-Levitt, and Marion Cotillard have all appeared in multiple Nolan films.

But the latest actor to join the cast of his new film Interstellar is someone who has never worked with Nolan before: Casey Affleck.

Affleck joins Matthew McConaughey, Anne Hathaway, Jessica Chastain, Bill Irwin, and the aforementioned Caine in the excellent cast.

While few plot details have been revealed, the film is described as "a heroic interstellar voyage to the furthest reaches of our scientific understanding.”

Production is expected to begin late this year, with a release date set for November 7, 2014.

Anyone who saw Joaquin Phoenix on Letterman last year knew something strange was up with the actor, but he sold it so well, we weren't entirely sure what.

Casey Affleck confirms that Phoenix was just acting when filming the faux documentary I'm Still Here, which Affleck directed. And what a performance it was.

"It's a terrific performance, it's the performance of his career," Affleck tells The New York Times of Phoenix's partying, impromptu rapping and unkempt look.

"I never intended to trick anybody," adds Affleck, who never thought people would think I'm Still Here was serious. "The idea of a 'hoax' never entered my mind."

Guess Joaquin is just that good an actor.
