Firth flashed the flesh for Gambit
Colin Firth has told how he left guests blushing at London's plush Savoy Hotel while making his new film Gambit.
The Oscar winner plays an art critic who embarks on a plan to con Britain's richest man into buying a fake Monet in the crime caper, and one scene required Colin to lose his trousers.
He revealed: "I had to wait on standby to make an entrance at the lift doors, and the Savoy understandably had not taken it upon themselves to advise every single one of their guests that there was a film taking place and a man without his trousers in the lobby.
"So guests would be on their way out for the evening and the doors would open and they'd see a somewhat over-familiar English actor standing there with his trousers off for no apparent reason in the corridor."
Colin said his co-star Cameron Diaz took great pleasure at his embarrassment.
"I felt that Cameron Diaz being the kind and sweet, supportive colleague that she was, would assure me that I had nothing to worry about, that my legs were were magnificent specimens. But she burst into a spontaneous belly laugh."
:: Gambit is released on November 21.
