Casey Affleck has won the Oscar for best actor in a leading role for Manchester By The Sea.
The 41-year-old beat fellow actors Ryan Gosling, Denzel Washington, Andrew Garfield and Viggo Mortensen.
Affleck was hugged and kissed by his brother, Batman star Ben Affleck as his name was called and received a standing ovation as he made his way to the stage.
The actor was tearful as he made his acceptance speech, saying: "This means so much to me, thank you. One of the first people who taught me how to act was Denzel Washington and I just met him tonight for the first time."
He thanked the film's director, Kenneth Lonergan saying: "Without this part and (your) writing I wouldn't be here for sure. Man, I wish I had something bigger and more meaningful to say. I'm proud to be a part of this community in general."
Affleck ended his speech by thanking his parents for "mostly believing in me" and added: "Ben, I love you."
