Ryan Gosling and Michelle Williams' romantic drama 'Blue Valentine' was the Centerpiece Gala screening at AFI FEST 2010 in L.A. Saturday night, and Ryan told ET, "I'm more proud of this movie than any film that I've made."
'Blue Valentine,' in limited release this December, follows a couple, Dean and Cindy, who are trying to save their marriage. During the course of one night, they are flooded with memories of their relationship, from their courtship to love lost in past and present moments in time.
"She worked on her character for six years, I worked on mine for four," said Ryan about their devotion to the film. "We felt like horses banging against the boards, you know? As soon as they said 'action,' we were off. … I couldn't have done it without her. Everything that I did was a reaction to something that she was doing, and she really raised the bar for me in a big way."
