The top two Screen Actors Guild awards — Best Actor and Best Actress — were handed out earlier this evening to Philip Seymour Hoffman for his legendary lead performance in Capote and Reese Witherspoon for her soulful country gal turn in Walk the Line. And the Best Supporting Actor trophies went to Cinderella Man‘s Paul Giamatti and The Constant Gardener‘s Rachel Weisz. It’s a fait accompli they’ll all be nominated Tuesday morning, and I guess they’re the quartet to beat at the Oscars on March 5th. Crash‘s “upset” win over Brokeback Mountain for the overall cast award might signify a Brokeback slowdown…maybe. But I doubt it.
