A semi-professional Colin Farrell impersonator has become embroiled in a bar tab row after a venue's staff mistook him for the actor.

James Martin was offered VIP treatment at the Upper West club in Chelsea, London by employees who apparently believed he was the Phone Booth star.

Once it emerged Martin was not the Irish actor an argument ensued, with staff demanding he pay off an alleged $4,800 bar bill.

Upper West owner Alex Nall-Cain tells Britain's Mail on Sunday, "All hell let loose when we realized Colin was in fact a lookalike. This imposter took advantage and ran up a bill of over £3,000... it was disgusting behavior."

Martin insists he did not drink while at the club and was unaware he had been mistaken for the Hollywood star.

He says, "The only victim was me for going there and looking a bit like Colin."
