Oscars: 'Manchester by the Sea' Wins Best Original Screenplay

Ben Affleck and Matt Damon presented the award.

Manchester by the Sea won the award for best original screenplay at the Oscars on Sunday.

Kenneth Lonergan's screenplay beat out fellow nominees Hell or High Water (Taylor Sheridan), La La Land (Damien Chazelle), The Lobster (Yorgos Lanthimos and Efthymis Filippou) and 20th Century Women (Mike Mills).

The award is one of the first-ever Oscars awarded to a streaming service, as the drama — starring Casey Affleck, Michelle Williams and Lucas Hedges, and about a family recovering from tragedy — is an Amazon title.

"The movie is about people trying to take care of each other in the face of terrible adversity, and I've been taken care of by some wonderful people," said Lonergan, thanking his loved ones.

Ben Affleck and Matt Damon, who won the award for Good Will Hunting in 1998, presented the award.

The 89th annual Academy Awards, hosted by Jimmy Kimmel, took place at the Dolby Theatre in Hollywood on Sunday.
