Well, the comics have one or two things different, most notably it was the silver surfer and not beta ray bill that hulk fought and freed everyone from the control discs. Other than that, the film was pretty spot on.
Wwh starts out after planet hulk left off, with hulk and shieara(sp?) together. They're running shit and she tells hulk he's gonna be a baby daddy. Hulk is super pumped and all happy, then boom! Bright lights, big city, and hulk and his fam are caught in a massive explosion.
Watching his family turned to dust in front of him pisses hulk off like nothing has before.
He can't think straight he's so pissed and his warbound determine the explosion came from his ship he crashed landed.
Realizing that the Illuminati were the ones that put the bomb inside of his ship, he orders his crew to assemble and they go and fly back to Earth.
Hulk immediately starts laying waste to everyone and everything. He's been pissed off more than he ever has in his entire life and for the entire trip there he's been pissed off. So he's stronger than he's ever been before.
Black bolt is up in the chute first and he gets his ass
whipped.
Everyone goes on high alert when hulk appears on world wide broadcast, holds up the broken black bolt and says that the black bolt wasn't shit, he was made of pussy, and that all the illuminati is gonna pay.
The illuminati scramble their collective forces, and it's all hands on deck.
X-men? Hulk whoops that ass. Fantastic four? Whoops that ass. Iron man? Alllll up in that ass. Dr. Strange tries to reason with Hulk. Hulk breaks his shit. Strange takes a magic power pill and goes hulkbuster on his ass, but stands down when he realizes they're destroying lives... Then hulk whoops his ass.
Hulk sets up the illuminati in a gladiator arena and makes them fight monsters and each other damn near to death via the control disks.
The Sentry finally pulls his thumb out of his ass and they go to work. They beat the shit out of each other so badly they revert back to human form.
Banner is ready to call it a day, but Miek (his warbound) gets pissed and hype saying it's bullshit to stop now, and that he didn't cause the explosion for nothing. (i forget his reason why, something with Rick Jones.)
Hilk gets pissed off more than ever and supercharges. With one stomp he fucks up the eastern seaboard. The illuminati light his ass up with a satellite that reverts him back to banner and they take him away.
There's a lot more shit involved, but i just gave it a real quick glossing over. All in all, a pretty decent book. Lots of bad ass brawls with hulk slapping so many fools around. I liked it, and haven't read it in years. Might have to give it another go.
