The 60-year-old actor was recently approached by a man in Paris who thought he was the 51-year-old U2 singer, but it only happens when people have taken "a lot of medication" or are "completely s**tfaced".
Speaking at the UK launch of Warner Bros' animated movie 'Happy Feet 2', he joked to BANG Showbiz: "I had a guy come up to me in Paris saying, 'Are you Bono?' Then he said, 'Oh no, you're not, you're Robert Windsor'.
"I only really get mistaken for Bono by people who are really hammered. They have to be completely s**tfaced to think I'm Bono. I suppose when I put on the glasses I look a bit like him. It's usually from a distance and by people who've had a lot of medication."

He added: "The Irish accent is one I just can't seem to get. I always start doing it and then it just f**king fades. It always ends up going into Scottish."
