What was that guy’s name again?

Carol and her family have this on going thing that when watching movies they have to figure out exatly who the actor is and where they’ve seen him prior to this movie. The answer needs be found before we can comfortably watch any film. I have become quite adept at the “name that actor” game. However, I have been stumped before. Perhaps that will happen less now that I’ve found this page as well as access to IMDB.
