While favorites Reese Witherspoon (Walk the Line) and Philip Seymour Hoffman (Capote) walked away with the top acting honors at Sunday's Oscars, Crash pulled an upset by lassoing the best-picture trophy away from Brokeback Mountain. In the supporting slots, Rachel Weisz (The Constant Gardener) and the never-fails-to-impress George Clooney (Syriana) grabbed gold. One of the night's other surprises came when rap group Three 6 Mafia's raucous "It's Hard Out Here for a Pimp" (from Hustle & Flow) merited the Academy Award for best song. (A complete list of winners can be found here.) Me, I couldn't help but be fixated on Keira Knightley's seeming inability to crack a smile for Jon Stewart. Geez, loosen up, girl.
