I love Vanishing Act, but really, what an unsympathetic bunch of characters! Did we care about the dead mangician? Did we have sympathy for any of the other protagonists? Only a sneaking admiration for Christopher Lloyd's tricks. Bobby, however, was in his element.
Was the title about which spouse betrayed their other half? Or about what's-her-face betraying Ross? Personally, I think it's about Ross betraying Rogers (?Rodgers - can never remember)
