“If they’re not in the room, don’t thank ‘em,” Sundance Film Festival director John Cooper told all the potential winners on Saturday evening, setting the tone for a brisk awards ceremony in which winners were restricted to 60-second acceptance speeches.Cooper appeared onstage dressed as a giant snowflake, as did host Tim Blake Nelson , who kicked off the show with a list of ways to get your film into Sundance. (Among his better ideas: “Boys Don’t Cry: The Musical.”) As usual, a number of winners didn’t show up to claim their prizes, having already left Park City for warmer climes at the time. Accepting a cinematography award for Bradford Young , “Pariah” director Dee Rees took the opportunity onstage to phone Young and let him know he’d won. “Resurrect Dead” helmer Jon Foy offered up some inspiring words upon receiving his directing award: “If you give up, you know what will happen. If you don’t give up, you don’t know what will happen.” And “Another Happy Day” writer-helmer Sam Levinson broke down almost completely when he was presented with the Waldo Salt Screenwriting Award. “When I introduced my film, I cried, so I don’t know what the fuck’s gonna happen now,” he said.
