Anyone remember that he originally wasn't a giant, but a miniman?
That's right, he shrank, not grew big!
Basically, exposure to Pym Particles could allow you to go both ways, shrink or grow.
Wonder what other characters they'll be featuring?
The Wasp would be a significant one, since she's married to AntMan.
Ultron, as the nemesis of Pym. might also feature as well.
But uncertain about that, since it might cause complications with Avengers movie.
But they can just keep killing him, since Ultron always makes replacement bodies anyway!
To explain, Pym series mechanoids have the means to transfer their minds out of their bodies into nearby computer systems, so if their body is destroyed, they just return to their home base and use the machinery there to fabricate a replacement body.
Ultron (and to a lesser degree, Jocasta) used this trick when their bodies were destroyed.
But is this movie about Pym or
http://marvel.wikia.com/Scott_Lang_(Earth-616)?
Both of them were known as AntMan, when Pym stopped using the AntMan equipment, Lang got a hold of it and took over the job.
However, I've always had a dislike for Pym, he's well, a bit of an unethical hero.
So am not that interested in seeing a movie about him.
Also concerned that it'll be another Marvel failure, they keep making them lately.
Not that I would know from experience, I gave up on them after seeing Iron Man 2.
