“It’s my favourite thing I’ve ever created or worked on. I love Derek more than any other character. In fact, I wish I were more like him," says Ricky Gervais of his latest creation, a helper in an elderly care home, a gentle comedy drama about those living on society's margins.

To mark the release of 'Derek' on DVD, which contains a documentary about the making of the show as well as a blooper reel (cue Gervais's swooping distinctive cackle), we have an exclusive clip of Ricky Gervais, Karl Pilkington and co behind the scenes.... with Mr Pilkington setting Mr Gervais off as usual!
