Actor: Sam Rockwell

Sam Rockwell won Best Supporting Actor for Three Billboards Outside Ebbing, Missouri, playing a violent racist policeman whom the film moves toward redemption, which generated considerable argument at the time.

Moon is the performance to argue for, carrying an entire film alone opposite himself, playing multiple clones with different degrees of deterioration.

Confessions of a Dangerous Mind, Matchstick Men and The Way Way Back show the range, and he dances in a great many of his films because directors discovered he can.

He was in Galaxy Quest as the crewman convinced he will die first, which is a very precise comic performance.
