Michael Keaton Almost Played Jack on 'Lost': Here's Why He Didn't

While he’s been enjoying quite the career resurgence in the last 10 years or so, Michael Keaton almost made quite a splash on TV back in 2004 when he was nearly cast as Jack on Lost, ABC's island-set mystery that dominated the pop-culture discussion from 2004 to 2010. Before letting your mind run wild, swapping Keaton in for Matthew Fox in various scenes or perhaps wondering how Keaton's Jack could have possibly fit into a love triangle with the younger Kate (Evangeline Lily) and Sawyer (Josh Holloway), know that -- had Keaton played the role -- things would have changed dramatically. In fact, the course of the entire series may have been altered thanks to just this one piece of casting.
