Simon Pegg has branded Ricky Gervais "fat" and an "idiot." The "How to Lose Friends and Alienate People" actor launched the vicious attack on his fellow British star after being asked if he, like Gervais, was struggling to cope with the pressures of living in Los Angeles.

Pegg said: "He says a lot of things, that man. He said there had been no good British films since 1950. What an idiot."
