Few Disney movies -- even those being released today --capture the spirit of adventure quite like Treasure Planet. The Sci-Fi, Steampunk-infused take on Robert Louis Stevenson's 1882 novel was years in the making when it hit theaters in 2002, the passion project of co-directors John Musker and Ron Clements. Its journey to the big screen hadn't been an easy one -- making its ultimate loss at the box office all the more painful for fans of its unique style. Though Treasure Planet has since been labeled one of Disney's "biggest animated flops," its daring creativity makes it a unique entry in the Mouse's catalog.
