Re: From WAR MACHINE to IRON PATRIOT and BEYOND
I think Rhodey's setup in the films isn't good for spinning him off. He's still an active member of the US military, so he really can't just be flying off doing his own thing. He can't just take the armor either; presumably it's considered the property of the US government (one would think Stark would be pissed about that and be trying to reclaim it; he has a pretty slam-dunk case that Rhodey just plain stole it and the government has no right to it).
The original comics setup of Rhodey being a Stark employee and having to follow in Tony's footsteps while forging his own heroic identity would have made for a more viable setup for spinoffs, IMO.
