By now we all know that Don Cheadle replaced Terrence Howard as James "War Machine/Iron Patriot" Rhodes in the Iron Man movies.
Most are aware of the drama behind the replacement as well. Though there was mention of Howard's difficult behavior on set, it had a bit more to do with money according to some. Due to being the first actor signed to a role for Marvel, Howard was apparently paid a bit more than most other actors in the first Iron Man. Yes, more than Jeff Bridges, Gwyneth Paltrow, and even Robert Downey, Jr.
When they began working on Iron Man 2 they asked him to take a pay cut. "1/8th" of what he made for the first movie according to the actor. As to why he was offered less, the story comes back to the rumors of his behavior, with director Favreau cutting back the role of James Rhodes for the second film due to the difficulty working with him and amount of cuts and reshoots needed for his scenes in the first movie. When the studio heard this, they approached the actor with a new deal, offering him the same money the rest of the supporting cast was making.
We all know how that story ends, but it isn't the news though. Recently, he's begun to blame Robert Downey, Jr. for being cut from the film and credits Iron Man with "killing his career."
Well, it turns out…and this is gonna get me in a lot of trouble. It turns out that the person that I helped become Iron Man, when it was time to re-up for the second one took the money that was supposed to go to me and pushed me out.” [...] “We did a three picture deal. You did the deal ahead of time. A certain amount for the first one. For the second a certain amount. For the third…they came to me for the second one and said, ‘We will pay you 1/8th of what we contractually had for you, because we think the second one will be successful with or without you.’ And I called my friend who I helped get the first job and he didn’t call me back for three months.”
When asked how things were now between him and RDJ, he offers an interesting answer,
Oh, I love him. God’s gonna bless him.
Many of his comments, such as the career killing remark, may simply be a bit of bitterness toward the incident. Although Howard hasn't had a role as high profile as continuing on in Iron Man 2 & 3, he has stayed very busy in Hollywood in the years since.
