Nick Frost says he had no problems appearing naked in his new film The Boat That Rocked.

He revealed all at the world premiere of Richard Curtis's new comedy set on a 1960s pirate radio ship.

Nick told The Sun: "I take my pants off and voila - we're ready to roll.

"I played rugby for many years so it's par for the course. You have to take your kit off in front of 30 men, which is essentially what a film shoot is."

Other cast members on the red carpet in London's Leicester Square included Rhys Ifans, Gemma Arterton, Kenneth Branagh, Tom Wisdom and Bill Nighy.

The Boat That Rocked also features a scene in which Bill walks into a room and finds Tom surrounded by 60 naked women.

Bill said: "I felt sorry for them. I was thinking 'Oh my God, put your clothes on.'

"It was a bit of a day. You think 'What am I doing today? Oh yeah, I've got to walk into a room with 60 naked women.' That was good fun."

The Boat That Rocked hits UK cinemas on 1 April.
