Comedian Ricky Gervais will make a final Christmas special episode of TV hit Extras before axing the show, according to reports. The Emmy-winning creator of The Office is determined not to risk the failure of a poor third series, and would rather move onto new projects. After the success of The Office, Extras attracted a host of A-list celebrities desperate for cameo roles including David Bowie, Chris Martin and Ben Stiller. The insider tells British newspaper The Sun, "There had been reports that Ricky was going to go ahead with a third series of Extras. But he is firmly of the opinion that third series are rarely a success and has decided to quit while he's ahead. "When he said goodbye to The Office with a two-part Christmas special, it was a smash hit both in the ratings and critically, so he's decided to do that again. He's loved making the series and there are tons more A-list stars who want to appear. "But Ricky has lots of other things he wants to do and feels this is the right timing."
