James Thompson = Slim Thompson?

James Thompson plays a train porter during 39:00-40:00 (2003 Universal DVD), bringing Martha Raye and Bob Burns together. He looks and sounds like Slim Thompson in the 1936 movie The Petrified Forest, http://www.imdb.com/title/tt0028096/, during 56:20-57:00 (2005 Warner DVD). Each scene includes the actor's left profile, and the left ear's opening has the same unusual shape. If he is the same actor, then that could help to explain why each actor has so few film credits.
