Bill Murray, 62, has given an interview to 'The Sunday Times' where he says he has fun with fans who mistake him for another actor.
"Half the time they confuse me with someone else. 'That one where you were in Vietnam. God you were funny in that.'"
Murray says he gets revenge on them by playing gleeful pranks which are documented on his website billmurraystory.com.
Murray who is currently starring as American President, Franklyn Delano Roosevelt (FDR), in Roger Michell's 'Hyde Park on Hudson', a film about the first visit by George VI and his wife to America, says he was surprised to be offered the role.
"I thought, 'Maybe they have an ulterior motive.' When I read the script it was just: 'That's not impossible. I'll do that.'… I like the fact that the move's not about Roosevelt, it's about what happens to the others that he touches."
Murray admits he'd love to do another comedy like Groundhog Day. "I'm hoping the funny stuff comes back."
He's currently being courted for a role in Terry Gilliam's 'The Zero Theorem' but, despite being tempted, has insisted that he wasn't won over by a script for a 'Ghostbusters' reunion.
"It is kind of tempting. Kind of sad but kind of tempting."
A couple of years ago a new 'Ghostbusters III' script landed on his doormat with "a lot of oomph behind it" but Murray put it down after 20 pages, saying, "It didn't touch our stuff."
Fellow Ghostbusters Harold Ramis and Dan Aykroyd are reportedly pressing on with a new film and 'Men in Black 3''s scribe Etan Cohen has been hired. But Murray insists: "It's not the way i would have gone."
'Hyde Park on Hudson' opens 1 February
