It was also a successful night for "The Sessions." Helen Hunt won best supporting actress and John Hawkes won best actor for his portrayal of a polio survivor who wants to lose his virginity.
The best supporting actor award went to Matthew McConaughey for his role as a male stripper in "Magic Mike."
"I had to take my pants off to win a trophy," McConaughey said.
