CB: If you've seen the Avengers: Age Of Ultron trailers or the recent television spot then you've seen The Hulkbuster Iron Man armor that Tony Stark (Robert Downey Jr.) will use in the film when battling The Hulk (Mark Ruffalo). Why the two science bros are fighting in Joss Whedon's film is still a mystery. Based on The Hulk's redish eyes I would think Scarlet Witch has tinkered with his mind. Or, Maybe not. We'll find out in May when the film opens.
