Who's your favorite actor who's really only had one famous role?

My personal pick would be Dwight Henry's performance in Benh Zeitlan's 2012 film Beasts of the Southern Wild. As far as I know Henry was a baker in New Orleans before he was cast in the film and hadn't been interested in acting beforehand. For a first time actor, he gave one hell of a performance and even on the Los Angeles Film Critics Association Award for Best Supporting Actor. Since then, he's only had minor roles in a few films, including 12 Years a Slave, and is allegedly going to play Marvin Gaye's dad in a biopic about the artist's life, but that's been in development hell for a while so who knows what's really going on.
