Fan Casting Obadiah Stane in MMU/1.: The Iron Man (2008)

Obadiah Stane was the best firend and colleague of Howard Stark, the father of Tony and the founder of Stark Industries. After Howard's death Stane became the CEO of the company and the mentor of Tony. But Stark took over his position when he grown up, so Obadiah wanted to eliminate him. He paid to the Ten Rings to kill Tony, but they wanted to use him to built more weapons. After he returned to the U.S. Stane wanted to fire him from the company and use the tech of the ARC reactor to make more weapons. So he built the "Iron Monger" armor to clash with Iron Man, but he lost and died in the battle.
