At a certain point, you have to put aside your own personal thoughts about how Terrence Howard was screwed over when it came time to make the second Iron Man film and he was dropped in favor of Don Cheadle. Because it's undeniable that over the course of the past two Iron Man movies, Cheadle has contributed a unique personality to the role of Colonel James Rhodes. He'll be stretching himself creatively as he stars in Miles Ahead later this year, which is a biopic about Miles Davis. It's clearly a passion project for the actor, who will not only play the lead role but is also directing the movie from a script that he co-wrote.
