Kenneth Lonergan-directed swaps out its leads…

‘Interstellar’ and ‘Ain’t Them Bodies Saints’ star Casey Affleck has revealed to the Boston Globe (via The Playlist) that he is replacing Matt Damon in the forthcoming drama ‘Manchester-By-The Sea.’

Affleck will play a man who returns to his hometown after his brother dies. There, he finds himself thrust into the care of his 16-year old nephew but finds himself crumbling due to a secret tragedy in his past.

Kenneth Lonergan (‘Margret,’ ‘You Can Count On Me’) is behind the camera, directing from his own screenplay. No word on when production will get underway.
