Actor Mark Hamill believes he is the world's worst Star Wars expert - and knows very little about the movies that made him famous. The film star - who played Luke Skywalker in the original science fantasy epics - has only seen each of the movies once, and is baffled by fans' obsession with the cult series.

He tells British radio station Heart: "I have failed Star Wars trivia tests. People come up to me at conventions and use terms that I've never heard of. Props from the film that we didn't have names for now have names - Dustbin Robot, he got the name IG54 or something when he became a toy nine months later."

He adds: "I say things like 'the blue guy with the trunk' and the fans go, 'Oh, you mean Sy Snootles'… and I have no idea."
