"I am tickled pink at the nomination -- this film has been such a labor of love and I am very proud of it. I couldn't be happier for our entire cast and crew and am thrilled for Tony, George and Tom," Swinton, a nominee for best supporting actress, said in a statement issued by Warner Bros.
"It's been a long road for 'Michael Clayton' and a long road for me personally," Gilroy said in a statement. "I'm afraid I'm coming up short … trying to capture how honored and overwhelmed I am with these nominations. I'm incredibly grateful to the academy voters and to everyone involved in making the film."
Warner Bros. said it plans to re-release the movie in North American theaters Friday.
