The military is pursuing Banner/The Hulk in the hopes of recreating his freakish ability as a military weapon.
Extensive super-heroic violence, with super-strong characters striking mighty blows, hurling people and objects about, destroying vehicles, and more. Extensive (albeit mostly pointless) firearms use against the Hulk and his nemesis; explosions, rockets, gas grenades, sonic cannons, and more are also deployed. Wounded bystanders and civilians are seen; the climactic battle features extreme graphic super heroic violence -- for example, the Hulk ripping off one of his opponent's mutated bone-spurs and using it as a dagger. Some martial arts and grappling. Characters fall from great heights; blood is often seen on-screen, as well as painful-looking experimental science-fiction medical procedures.
Some kissing in semi-clothed circumstances; some references to how "excited" the lead character can get without risking turning into his monstrous alter ego.
Language includes "crap," "pissed," "a--hole," "bitch," "hell," "goddamn," "damn," and a choked-off "s--t."
Tie-in to vast quantities of related merchandise. Several brands appear on-screen, including Norton computer utilities, Polar heart rate monitors, and SanDisk USB drives.
