Justin Hammer was the secondary antagonist of the 2010 Marvel film, Iron Man 2.

He was portrayed by Sam Rockwell.

Iron Man 2 & Defeat
In that version, Justin Hammer was portrayed a little different compared to the comic book version: Justin appeared to be younger than Tony Stark instead of being older, he whined when he didn't get his way, and appeared to be less intelligent. Hammer was one of Tony's rivals. He owned Hammer Tech; a company that made weapons. Hammer had been trying to create an exact replica of the Iron Man Armor, but in the process, injured just about everyone who tried the suit. After he witnessed Iron Man fight Whiplash, Hammer was impressed with Whiplash and planned to break him out of prison, while at the same time place a fake Whiplash to take his place so that they could perform a fake death. Hammer and Whiplash made a deal with each other that if Ivan made a huge amount of Iron Man Armor, they would put an end to Tony's career. What Hammer didn't know was that Whiplash was planning to turn against him and destroy Tony with the same armor. When Pepper Potts, Tony's girlfriend and temporary CEO of Stark Industries found out that Hammer was working with Vanko, she called the cops on him. Some time later, S.H.I.E.L.D. found out that Hammer had helped Whiplash escape, they arrested him for helping a prisoner escape.
