British actress Keira Knightley has called for an end to nudity in her movies - as she fears fans will get sick of seeing her without any clothes on. The Pirates Of The Caribbean star, who admits she has no qualms about appearing naked, worries any more scantily-clad roles may be off-putting for moviegoers. She says, "I don't mind stripping off. I have certain tools. One of them is my body. "But people will insist I keep my clothes on soon."
