The Office creator Ricky Gervais has no plans to make a third series of his hit British TV comedy Extras, because he hates shows which run past their sell by date. The Golden Globe winner has just finished work on the second season of Extras - which features cameo roles from Chris Martin, Orlando Bloom and Harry Potter star Daniel Radcliffe - and is already turning his attention to a fresh project. He says, "At the moment I don't think there will be another one. "Steve (writing partner Stephen Merchant) and I have always had this thing where we only like to do two series. "It's like The Office, people are always asking why didn't we do any more, but we just wanted to leave people wanting more. "Why drag it out and ruin it? I've seen that happen to other comedies and I hate it."
