Continuity: In the middle of the film when Bruce is being taken down into the underground facility in the desert, we see guards standing around his container where he is sleeping. Look at the front, and there is a guard in front of the container with his left arm resting on it.

Continuity: Near the beginning of the film when Bruce first turns into the Hulk, he tosses the gamma machine out of the lab and into the road outside, but if you use frame by frame or slow motion from a view on the inside the gamma machine reaches the outside, and a view from the outside is showing the machine just coming out of the wall.

Factual error: The Hulk picks up a tank, swings it around and hurls it about a mile away where it crashes into a sand dune. The impact should have been as strong as a plane crash, but a few shots later, they show one of the tank crewmembers standing casually outside the tank, watching the Hulk.

Other: In the scene in the desert, when the Hulk picks up the tank by the turret, the hull of the tank stays attached. The turret actually isn't attached to the base, it sits on a rotator ring and is held in place by gravity. (Turret weighs about 25 tons, if I recall).
