The folks at Latino Review have got an interesting lead on what is happening on the Iron Man 3 set and apparently not everyone is as tight lipped as the heads of Marvel Studios.
A crew member let it slip that, as predicted, Sir Ben Kingsley is indeed playing The Mandarin in the film but he will NOT be the primary antagonist. Guy Pearce's Aldrich Killian will be the main focus of evil in the film with The Mandarin being more to the side of it all. Perhaps waiting for his time to take the spotlight in Iron Man 4?
Iron Man 3 is currently filming in North Carolina, starring Robert Downey Jr., Gwyneth Paltrow, Don Cheadle, Ben Kingsley, Guy Pearce, James Badge Dale, Ashley Hamilton and Jon Favreau. The film is scheduled to hit theaters on May 3, 2013.
