murphy's law
Otherwise known as 'sequelitis'. A general malady where any actor who reprises a character in more than one movie (that is, for example, is compelled to do, say, The Nutty Professor IV: Buddy Love Vs the Hamster) is doomed to repeat that character in other movies.
It is murphy's law in action: the movie The Haunted Mansion. (Other actors suffering from murphy's law is Bruce Willis, Sly Stallone, Arnie Schwarzenegger. Of course, Arnie may have inadvertedly found the cure for ML)
