When co-stars collide at Oscars: Does one win or do they split the vote? Sam Rockwell, pay attention!

It’s the dream of most actors and actresses to receive an Oscar nomination and, if they’re lucky, to win. But what happens when you’re up against a co-star from the same movie? Does one triumph or do they split the vote? Click through our photo gallery above of all the times this has happened throughout Academy Awards history.

Sam Rockwell and Woody Harrelson both scored Best Supporting Actor nominations for their work in “Three Billboards Outside Ebbing, Missouri.” It has been 26 years since Harvey Keitel and Ben Kingsley were both nominated for “Bugsy” (1991). Unfortunately for the duo they split their support and Jack Palance won for “City Slickers,” ironically a former victim of vote-splitting against his “Shane” co-star Brandon De Wilde (they lost to Frank Sinatra, “From Here to Eternity”).

What a tangled web the Oscars have once again weaved. Rockwell is the frontrunner after winning the Golden Globe, BAFTA and SAG Awards. And he currently is predicted to win with odds of 2/11. Right on his heels is Willem Dafoe for his work in “The Florida Project” with odds of 10/1. Dafoe was previously nominated for “Platoon” (1986), where he was joined by his co-star Tom Berenger. Berenger and Dafoe split their support, allowing Michael Caine to finally win for “Hannah and Her Sisters.”

It would be understandable if Dafoe did not find this situation funny should he lose to Rockwell! Regardless of whether Rockwell wins, it will pale in comparison to Robert De Niro’s Best Supporting Actor victory for “The Godfather Part II” (1974) as he was victorious over not one but two co-stars — a feat no one else has ever accomplished.
