London, Feb 09 : Actor Bill Murray has said that he doesn't mind people saying he is difficult to work with, as he looks at it as a "badge of honour."

Murray admitted that he is "nothing but trouble" on film sets.

"People say I'm difficult and sometimes that's a badge of honour. At work I'm just nothing but trouble with anything I don't want to do. And I fired my agents," the Daily Express quoted him as saying.

He added: "I said I didn't ever want to speak to them ever again, and I never did. It saved me money but mostly it stopped the irritation of the endless phone calls."

Murray was rumored to have been caught in a row with actress Lucy Liu and director McG, during the filming of 'Charlie's Angels' in 2000.
