The video is back!
A new international trailer for "Iron Man 3" made the rounds Monday, and was almost immediately taken down by Marvel. It's unclear why the 'Iron Man 3' trailer went up in the first place only six weeks before the film's release, but one thing we can tell you is that it contains a MASSIVE spoiler. Stop reading right now if you don't want to be spoiled.
Last warning: massive spoiler ahead.
Pepper Potts will suit up in "Iron Man 3." That's right — Gwyneth Paltrow will don the Iron Man armor herself and come to Tony Stark's rescue.
In the extremely action-packed new footage, we see Tony Stark gesturing toward pieces of the Iron Man armor, which fling themselves onto his body as if he were a giant magnet. This reflects the Extremis story arc the movie's plot reportedly follows.
Far cooler though, there's a scene where Pepper Potts appears to be flying through the air inside a shockwave from some huge explosion. Tony points toward her and the armor seamlessly detaches off of his body and attaches itself onto Pepper Potts. The scene is quite possibly the neatest bit of CGI in the entire Iron Man trilogy.
Later, we see Tony Stark lying on the floor of his L.A. mansion with an attack helicopter shooting missiles at the house. Pepper Potts stands over him with full Iron Man armor on and the faceplate lifted. She then puts the mask down and shoots at the helicopter. The last part, we've already seen in previous trailers, but we never had the slightest inkling that it was anyone other than Stark himself.
You can still view the trailer here, but you'd better hurry.
