Continuity mistake: When the Hulk breaks out of the government lab, he pushes up a round staircase and a soldier jumps behind it. He is then seen right in front of it when the camera angle changes. (01:34:50)
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. (00:16:40)
Audio problem: During the scene where Talbot approaches Betty by the elevator, it splits and in doing so the top left screen does not speak, but the bottom right does, and they are supposedly "Sync"ed.
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. (01:22:05)
Audio problem: During the scene where Bruce's father is giving him the green dinosaur toy and the monkey toy and suggests making them have a fight, the boy "Roars" but his lips don't move at all, in fact his mouth is shut.
Continuity mistake: At the start of the film when his foster mother comes in to wake Bruce up, her hand on his head changes slightly between shots. (00:09:50)
Factual error: 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).
Continuity mistake: When Betty is talking to Bruce about accepting their breakup, the camera from the front shows her looking right at him, but the camera from the back shows her looking down.
Continuity mistake: Betty is touching the door panel to scan her identification but in the next shot she has not reached the door yet.
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.
Suggested correction: He is shown jumping 150-200 feet high, not 20,000ft.
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). (01:15:55)
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.
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. (00:47:20)
Continuity mistake: In the beginning when Bruce and Betty are talking, her fringe changes several times during the scene. (00:12:30)
Factual error: In every scene that Gen. Ross is wearing his service dress uniform, the Armed Forces Expeditionary Medal (second to bottom row, viewer's left) is upside-down. The three center stripes should be (from viewer's left to right) blue, white, red; not red, white, blue.
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.
Continuity mistake: In the scene where Nick Nolte is in Bruce's lab, after he exposes himself to gamma rays his hair is almost completely black, but in the rest of the movie it is greyish-brown.
Continuity mistake: During Bruce's conversation with David near the end, he wears light blue pants, but when he transforms into Hulk until the end of the fight with David, he wears the same purple pants that he wear during the desert battle. (01:58:43 - 02:08:04)
Continuity mistake: In the pic with Betty there is no sun on it, but in the flashback the sun is shining on the tree.
