February's Total Film magazine features some new information from Marvel's Avi Arad. He confirms that Hulk 2 is in progress, and a few intruiging changes that will be made from the first film.
"In the next movie, Hulk 2, the Hulk will be smaller. If you make him 15-feet tall, there's no human connection there.....Right now we are still developing the sequel. I think the key thing is to come up with the right story."
The article also says we are promised, 'less angst and a lot more Hulk smashing,' and that Bruce Banner will become more comfortable with his big green side.
