12 Years a Slave won the Best Film award at this year's British Academy of Film and Television Arts (BAFTA) Awards in London on Sunday, but the night belonged to Alfonso Cuaron's astronaut thriller Gravity.

The film, which stars Sandra Bullock and George Clooney as a pair of astronauts fighting for their lives after a freak accident during a space walk, was the big winner, pulling in six awards, including Best British Film, Best Director (Cuaron), and the awards for visual effects, sound, music and cinematography.

12 Years star Chiwetel Ejiofor won the best Leading Actor award, while Cate Blanchett landed the best Leading Actress award for her role in Woody Allen's "Blue Jasmine." Barkhad Abdi and Jennifer Lawrence won in the supporting actor and actress categories, for "Captain Phillips" and "American Hustle," respectively.

Disney's "Frozen" landed the Best Animated Film award.

"You can't tell from my accent but I consider myself a part of the British film industry," Cuaron said while accepting his Best Director award. "I've lived in London for the last 30 years and I've done almost half of my films in the U.K. I guess I make a good case for curbing immigration!"

Blanchett dedicated her best actress award to late star and good friend Philip Seymour Hoffman, who died of a heroin overdose two weeks ago.

"Phil, your monumental talent, your generosity, and your unflinching quest for the truth, both in art and life, will be missed, not only by me but by so many..." she said. "Phil, buddy - this is for you, you b*stard! I hope you're proud."
