When an actor with a popular role in the past has a resurgence doing something else. Often they will be cast purely for nostalgia reasons, or because the director or writer is a Promoted Fanboy. Ironically, though, they often become even more popular than they were before, causing their earlier work to be all but forgotten.
Named for The Simpsons' Troy McClure, who used to be a character actor, and then did educational films, infomercials, etc. He would introduce himself with "Hi, I'm Troy McClure! You might remember me from such films as Aliens Steal Cable! and The Adjectival Superhero." (The names of the two films were usually relevant to what he was in at the moment.)
