We reported about this a while back, but apparently rumors are still circulating that The Incredible Hulk will end up being the Villain in The Avengers film. Hawk Otsby and Mark Fergus (Iron Man Screenwriters), have stated that they would like to see all of these Marvel films lead up to the events in The Avengers (obviously). Another point they bring up is regarding the ending of The Incredible Hulk.
“Fans will remember that the finale of The Incredible Hulk ended ambiguously [Spoiler Ahead], with Ed Norton smirking slightly after bringing down the abomination. The very end scene of the film also seems to be setting up this storyline, with General Ross talking to Tony Stark about the green-skinned menace.”
When I first saw The Incredible Hulk, that’s not what I originally though it was hinting at (Hulk going bad), but I can see that now. With Bruce Banner finally being able to control the monster inside him, it would make sense if he took a turn for the worse. I’m starting to think the Hulk as the main villain could be a good thing.
