Sir Michael Caine has changed his birth name to avoid being asked endless amounts of questions at airport security.

The actor, whose real name is Maurice Micklewhite, revealed he got fed up being forced to stand at airports being checked by security because of the name on his passport.

The star, whose catchphrase is "my name is Michael Caine", explained that he was constantly questioned as to why his name was different on his passport to the one he is recognised by worldwide.
