Continuity mistake: Near the beginning, when Banner arrives at the lab with his helmet on, he removes the helmet when he sees Betty. A close-up of his face is shown and his hair is messy with part of his fringe on his forehead. Betty is shown quickly, then the same shot of Banner is shown again, but this time his hair is perfect.
Continuity mistake: Near the beginning, when the other scientist accidentally trips the gamma machine on, Bruce helps to get the guy's gas mask on. In one shot, when Bruce throws the scientist to the ground, he is holding onto the gas mask with his right hand, then in the following face shot he is holding it with his left.
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, as if nothing happened to them. All of the men inside the tank should have been seriously injured from the impact, if not dead.
Continuity mistake: 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. Then it cuts to another shot, this guy is no longer in front of the container nor has his arm on it, this happens between shots. (Zoom in is required).
Continuity mistake: When Bruce and Betty are in the middle of the desert, Betty walks to the door where Bruce's parents were arguing, he walks to the door and opens it. He looks in but Betty is still looking at Bruce in this shot, yet in the following shot she is looking in the room.
Continuity mistake: In the middle of the film when Bruce is in the cabin with Betty, just after he discovers a noise outside and gets shot by a tranquiliser, if you watch closely the tranquiliser is at the side of the leg, then in the following shot when we get another view of it from the floor it is at the front of the leg.
Deliberate mistake: When Hulk meets his father at the lab, each one's eyes have a special light on them. This adds for dramatic effect, but it's absurd because there is no direct source of light since each one is in front of the other and their faces are in shade in the rest of the shots.
Continuity mistake: When Talbot calls out to Betty as she walks in the entrance to her building, in the background a cyclist gets on his bike and puts both feet on the pedals then starts to ride off. When it cuts to a view of Talbot, the cyclist still has his left foot on the ground and isn't moving.
Continuity mistake: When Talbot goes to visit Bruce in his holding cell in the underground base in the desert, Talbot pokes him with a cattle prod of some sort. In this shot the screen splits into two. Bruce puts his hands up in the air when he gets zapped, but the other view on the screen shows that he still has his hands by his side. (Slow motion may be required.)
Factual error: The jet aircraft that the Hulk hangs onto couldn't have flown as high as it's shown to. The max altitude of the F-22 is currently 50,000 feet, any higher than that and the pilot would have to wear a specialised flight suit. To see 'space', an aircraft must reach a height of 90,000 feet, which is almost double the 'safe' altitude for pilots, not to mention the F-22 lacks the engines of the SR-71 or U-2 to cope with the low oxygen levels of the upper atmosphere.
Factual error: When the Hulk is jumping from mountain tops to mountain tops, it is amazing at which speed he falls back on the next mountain. There is nothing wrong with him jumping very quickly at a 20,000 foot altitude (because he is very strong), BUT, the Hulk should not go down faster than a free falling object. Unless he has superman powers, falling from the top of his trajectory to the next mountain top should take something like 2-3 minutes. In other word he should not fall faster than the average skydiver.
Continuity mistake: In the middle of the film when David Banner transforms himself at the lab's gamma machine, he attacks a black cop. Watch closely, just after David Banner lifts the floor up sending the cop flying towards him you can see he is lying on his back in one shot then lying on his side in the following shot. (Slow-mo is required).
Visible crew/equipment: When Betty is driving to see Bruce's father, she is looking in her notebook. When she puts it away, it cuts and a truck passes on the right side. Watch carefully in the lower right corner, right after she passes the truck. Something is quickly coming into frame. Hard to tell what it is, but whatever it is, it is not supposed to be there.
Other mistake: In the scene in the underground base, where the Hulk is destroying the area, when the General orders them to turn out the lights and show him the way out, the keyboard that she grabs to type in the commands is not plugged in. Right as she grabs the keyboard, you can see the plug laying on the floor beside it.
Factual error: In the final duel between the Hulk and his energy-absorbing father in the remote lake, an aerial military task force drops a tactical nuclear missile on the lake, effectively sub-atomizing the Hulk's dad in an instant. While acknowledging that, yes, the Hulk himself might even survive a nuclear detonation, there is no doubt that the small lake (as well as Hulk's one-size-fits-all purple pants) should have been completely vaporized at temperatures of tens of thousands of degrees. However, immediately after the blast, we see the normal Bruce Banner drifting peacefully in the lake (which is not boiling nor even steaming) with his form-fitting purple pants entirely intact.

Revealing mistake: When Hulk rips the turret off the tank and swings it around in the desert has a solid base. This is correct for a model but not for a real tank which has a hollow turret for the tank captain to stand up from the bottom of the tank through the turret and look out the top.
