The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at the Trope Launch Pad.

I'm looking for a trope where an actor is used obviously as a substitute for another actor. In particular, I'm thinking of Josh Duhamel in When in Rome, who not only sounds a lot like Tom Hanks, but plays the same sort of character that I'm used to seeing Hanks play.
