The past decade has not been kind to John Travolta. It began with Battlefield Earth, and ended with the movies about the middle-aged guys on motorcycles (Wild Hogs), the middle-aged adoptive fathers (Old Dogs), the middle-aged guy who found valuable dancing shoes (Gold Clogs), the middle-aged children's book author who runs at a medium pace (Roald Jogs), and the middle-aged guys who flip milk caps in a meat storage locker (Cold Pogs).
