The Hollywood Reporter has revealed that Jon Favreau (director of Iron Man and Iron Man II) will be reprising the role of Happy Hogan in Iron Man III. Need more proof? The man himself tweeted it yesterday. There was some worry amongst fans of the character and the franchise that Favreau wouldn’t return, considering he had turned down an offer to direct the third installment. At this point in time, it’s unclear how big a role he’ll play in the movie (he had a fairly large one in Iron Man II but at best a small cameo in the first movie), but with the already massive cast this movie has I expect Shane Black and co will want to tone his role down.
