John Cleese was left in so much pain after filming scenes for cult British comedy Monty Python he had to stop the comedy routines.

The star appeared in the series alongside Terry Gilliam, Terry Jones, Michael Palin, Eric Idle and the late Graham Chapman, from 1969. During the sketch shows Cleese would carry out a silly walk to make people laugh while he was in character.

Palin has revealed the scenes left Cleese in agony - but the actor tried to continue because the fans enjoyed it so much. He says, "John found it physically impossible. He did it in terrific and violent pain while people roared with laughter." (KD/WNTST/CL)
