<Li> Jeff Bridges as Obadiah Stane : Stark 's business second - in - command , mentor and friend who turns on him to overtake the company , eventually building a giant exosuit to fight Stark . Bridges read the comics as a boy and liked Favreau 's modern , realistic approach . He shaved his head , something he had wanted to do for some time , and grew a beard for the role . Bridges googled the Book of Obadiah , and was surprised to learn retribution is a major theme in that book of the Bible , something which Stane represents . Many of Stane 's scenes were cut to focus more on Stark , but the writers felt Bridges 's performance allowed the application of `` less is more '' . </Li>
