I know that guy

[The Condor]

Character actors; we all know them and appreciate a lot of their work. I came to realize the other day, however, that I only know some of them by a certain role and not by their names. For example, I always refer to Steve Jenkins, who has had a fairly distinguished career and an Oscar nomination, as "Dr. Doback" for his role in Stepbrothers. Another would be Clancy Brown, the voice of SpongeBob's Mr. Krabs and an accomplished actor, whom I know simply as "The Kurgan" for his work as the baddie in The Highlander.

Does anyone else have a guy in mind or do this as well?
