AceShowbiz - Actors-turned-directors were the big winners at the Sundance Film Festival in Utah on Saturday, January 30 - Mark Ruffalo and Josh Radnor took two of the night's big awards. "Collateral" star Ruffalo stepped behind the camera to direct and star in "Sympathy for Delicious", the story of a paralyzed DJ with the power to heal others but not himself.

And his directorial debut made a big impression at Robert Redford's film festival - earning Ruffalo a special jury prize for his efforts. Another big winner was "Happythankyoumoreplease", written and directed by "How I Met Your Mother" star Josh Radnor, who also takes a lead role in the film. The movie garnered the audience award for favorite U.S. drama.

"Winter's Bone", which tells the story of a 17-year-old girl living in America's Ozark Mountain range, landed the grand jury prize for best American drama as well as the screenwriting award for director Debra Granik and co-writer Anne Rosellini. "Restrepo", which follows the lives of U.S. soldiers fighting in Afghanistan, was named best U.S documentary.
