Gervais 'stressful' to work with

Ricky Gervais's writing partner Stephen Marchant admits that every time they begin work on a new venture, he insists they will never collaborate again because it is just so taxing.

He explained: "I always find filming quite stressful, partly because of the time constraints and partly because of working with Ricky. Every time we finish a project I say I'm never working with you again, I openly say it to him.
