Travolta is pretty much the comeback king, having gone up and down the A-list ladder faster than a demented window cleaner. He first made it big in the seventies, with Grease and Saturday Night Fever giving him a place in the heart of audiences. A string of poor choices (Staying Alive, Two Of A Kind, Perfect) sank his career in the mid-eighties, and putting on a bit of weight didnt help either. It wasnt until Tarantino gave him another shot with Pulp Fiction that he regained his crown, and he again made a batch of hits like Face/Off and Get Shorty. His next fall from grace was pouring the goodwill hed earned into making Battlefield Earth, based on the book by the founder of Scientology. The movie left such a stink it practically killed his career overnight, with most of his follow-up movies bombing. While hes mostly known these days for his weird hairline and creeping behind Scarlet Johansson, hes evolved into a great character actor, which can be seen in Savages and American Crime Story.
