"This is amazing," the 14-year-old actress said. "I first and foremost want to thank (filmmakers) Joel and Ethan Coen, (producer) Scott Rudin and everyone at Paramount ... My parents, my mom and dad, my brother, Griffin. My God, this is amazing. Thank you so much."
The Broadcast Film Critics Association's presentation opened with a pre-taped spoof featuring the cast of "Jackass" sending up 2010's celebrated cerebral thriller "Inception," which won the Critics' Choice Awards for Best Action Movie, Best Sound, Best Cinematography, Best Art Direction, Best Visual Effects and Best Editing.
The comic version of "Inception" was followed by a live greeting from action-film icon and former California Gov. Arnold Schwarzenegger, who joked that he is now just an employed actor begging for work.
"I know you're thinking, 'Is this the year Arnold opens with a big song and dance number?' No, I'm not going to do that for you," he said. "Good evening. I'm very happy and honored to welcome all of you to the Critics' Choice Movie Awards, which, of course, makes history because it is the first time the words 'Arnold Schwarzenegger' and 'Critics' Choice' have been used in the same sentence. I told you 'I'll be back.' And it's nice to be here after all those years in Sacramento."
"Easy A" earned the title of Best Comedy, "Toy Story 3" picked up the prize for Best Animated Movie, "Waiting for Superman" was named Best Documentary and "The Pacific" won the award for Best Picture Made for Television.
