Source: Marvel Int'l President Dishes Out IRON MAN 3 Spoilers?
A Brazillian website broke the story that at a presentation in São Paulo, President of Marvel Entertainment International and Consumer Products Simon Phillips spilled some beans on Iron Man 3.
If you don't want to have the movie spoiled, please click away now.
Here's a summary of what he said:
Tony Stark (Robert Downey Jr.) will eventually have an underground Hall of Armors with at least 16 new armors, including a few classic designs from the comics. Simon Philips also revealed, or confirmed, that Virginia Pepper Potts (Gwyneth Paltrow) will indeed get in on the action, this time by donning her own suit of armor; similar to doing so with the ‘Rescue’ suit in the comic books.
In addition, the report also captioned a scene from last month's teaser trailer, where Tony Stark is seen lying on a hospital bed, seemingly readying an operation. As expected, Philips apparently confirmed that it's during that scene that Stark is being injected with the Extremis virus. And as a result, he'll be able to create new armors from leftover pieces of older ones. For example, as Protocida notes, Stark will use arms and legs from previous models to create a new design.
It's just a rumor and doesn't contain huge spoilers, still things sound pretty exciting for 'ol shellhead. We'll find out for sure when Iron Man 3 opens on May 3, 2013.
