Film cameos have slowly become the bane of the movie world. Oftentimes they are harmless little winks at the audience designed to give the crowd that warm, fuzzy feeling inside. But more often than not, these bit parts are nothing more than huge distractions that serve as a massive speed bump in the middle of a flick.
