Of all the actors featured on this list, Kevin Costner is one who started out with the most promising career. No Way Out and Bull Durham were just the beginning of a string of hugely popular movies which peaked with Dances With Wolves and JFK. Following on from 1993's A Perfect World the dud movies starring Kevin Costner started coming in thick and fast - Waterworld might not have been the commercial failure some have suggested (the theme park attraction based on the film actually made a sizeable chunk of the budget back alone). but it marked the period of his career where vanity started to go out of control. Yet while Kevin Costner has never returned to being the huge star he once was, nevertheless he's worked steadily for the last twenty years despite having appeared in literally nothing worth writing home about.
