May 3rd... an ambiguous day to release the 3rd installment of Marvel Studios' Iron Man series. After the ultra success of the Avengers movie, not to mention the success of the prior two Iron Man films, this one has big shoes to fill, for sure. But with a supporting cast to rival any motion picture currently in production (Don Cheadle, Guy Pierce, Gwyneth Paltrow and Ben Kingsley) and the return of Robert Downey Jr. in the title role,  this three-quel is sure to please.
