Tombo,
There was a rumor that the guy from Sex and the City, the blonde guy who dates the Kim Cattrell character may play him. He'd need to put on at least thirty pounds though.
As for the other Hulk movie, the Ang Lee/Eric Bana one, well, that one didn't do as well as Universal had hoped. They lost the rights back to Marvel because they were hesitant to greenlight a sequel and their contract for use of the character ran out.
Marvel is now getting into the movie making business. They are making this movie while Universal is only distributing it for them for a percentage. Marvel wanted a reboot. That's why we have a new director and a whole new cast.
Like you, I also liked the Lee/Bana one, but people thought it tried to be too highbrow and didn't have enough action or a good villian. It was also expensive because ILM (The George Lucas fx company) did the special effects.
The fx for this one are done by Rhythm and Hues. IMO, they are not as good. You get what you pay for.
The script is not very good either. If you want a copy of it just let me know. But you'll need Adobe to read it or something else that can handle pdf documents.
