Making it big in the "hot or not" world of Hollywood is hard. Staying big? Even harder! That's because real success isn't just measured by getting there, it's about staying there. It's also about figuring out how to get back once you’ve been forced out the door. Few faded television and film stars have careers that bounce back to new heights. A lucky few, however, do -- and that's what Killer Comebacks is all about. Some of the actors we will meet are Sarah Jessica Parker, Alec Baldwin and John Travolta.
