Movie star Johnny Depp is wishing he'd never agreed to taking part in the upcoming Sports Relief run on 15 July (06), because he is completely unprepared. Depp was persuaded by his Pirates Of The Caribbean co-star Keira Knightley to take part in the charity event, but he is less than enthusiastic. He says, "I'm not sure when it is. I'm quite worried, I'm not fit at all."
