Darkness and Light: Part 1 - S1-E11
Continuity mistake: When the soldiers burst into the lab, Talbot is standing next to the Hulk. When the shot changes, Talbot is suddenly standing in front of his soldiers and ordering them to stand down. (00:14:50)
Darkness and Light: Part 1 - S1-E11
Other mistake: When Betty is trying to revive Bruce, a console explodes and a corridor is revealed that soldiers emerge from. It makes no sense for a heavy piece of machinery to be blocking the way into a corridor if blowing up the console is the only means of getting in or out.
Darkness and Light: Part 1 - S1-E11
Continuity mistake: When Betty is giving Bruce chest compressions, you can see armed soldiers standing in an empty doorway behind her. When the shot changes, a console explodes, revealing the same doorway that the soldiers are suddenly emerging from.
Darkness and Light: Part 1 - S1-E11
Continuity mistake: The nutrient bath container that separated Banner and Hulk was large enough for both to comfortably fit inside, but when Betty is trying to perform CPR on Banner, you can see an unconscious Hulk still in the container, and it is suddenly barely large enough for him alone to fit inside. The design of the container also changes. (00:14:20)
Darkness and Light: Part 1 - S1-E11
Continuity mistake: Just before Doc Samson tackles Talbot, Talbot fires his blaster, which hits the middle of a console. A couple of shots later, the blast mark is at the top of the console. Its size and shape change as well. In the wide shot it is nowhere to be seen. (00:14:00)
Darkness and Light: Part 1 - S1-E11
Other mistake: When Gabe Jones is observing Doc Samson and Hulk emerging from the cave system in his rear view mirror, you can see his car is moving forward, but the image in the mirror remains the same size. (00:11:10)
Darkness and Light: Part 1 - S1-E11
Other mistake: When the Outcasts are launching boulders at the helicopters, they hit one that explodes immediately, and both occupants can be seen emerging from the fireball, safely parachuting to the ground. Even if they were able to jump from the helicopter before it exploded, their proximity to the explosion would have killed them before they had the chance to deploy their parachutes.
Darkness and Light: Part 1 - S1-E11
Continuity mistake: When the army helicopters are approaching Hulk in the desert, it changes from twilight to nighttime instantly.
Darkness and Light: Part 1 - S1-E11
Audio problem: When Doc Samson is saying "I am delighted to be almost home," his mouth isn't moving for the first few words.
Darkness and Light: Part 1 - S1-E11
Other mistake: The river that Hulk battles Doc Samson in is only ankle-deep, but when Samson knocks Hulk out with the sonic gun, the river current is able to carry Hulk downstream. Hulk is lying flat on his back, and since the water is only ankle-deep, his back would be touching the floor of the river. In this case, the current of a shallow river would not be able to carry someone of the Hulk's mass.
Darkness and Light: Part 1 - S1-E11
Continuity mistake: When Hulk is smashing his fists against the cliff walls, he causes Doc Samson to fall off the cliff and into the river near Hulk's feet. A couple of shots later, Samson has disappeared from view and a boulder is there in his place. (00:02:20)
Continuity mistake: When Bruce Banner is in the soup kitchen, there are several paneled windows behind him. When he is shown standing up from his seat, it is only a brick wall behind him.
Continuity mistake: When Gargoyle is standing in the doorway of the hospital room bidding farewell to Banner, they are standing at a straight angle respective to each other. When the shot changes, Banner has moved several feet to the left. (00:20:17)
Continuity mistake: When Abomination attacks Bruce Banner at the infirmary, he shoots him with a laser blast that leaves a hole in his shirt's chest area. In the next scene after Banner has been taken to Gargoyle's lair, his shirt is no longer damaged. (00:12:45 - 00:13:45)
Continuity mistake: When Gargoyle and Abomination are looting the electronics store and Gargoyle notices Bruce Banner walking by, a display stand appears next to Gargoyle in a close-up shot that is not there in wide shots.
Continuity mistake: After Hulk breaks free of the cable Thor wrapped around him, he lands on the street and is hit by a car, which damages its bumper and windshield. When the shot changes the car is suddenly pristine until Thor lands on its hood. (00:06:35)
Continuity mistake: The cable Thor tears off from the suspension bridge to wrap around the Hulk changes from a copper color to silver. (00:06:25)
Continuity mistake: The steel beam that Hulk pries off the top of the bridge and throws at Thor wasn't there when he first landed. (00:06:00)
Factual error: When Hulk lands on top of Mount Rushmore, Teddy Roosevelt's glasses are missing.
Continuity mistake: When Dr. Blake is walking towards the phone, it is resting on its receiver. When the shot changes to him picking the phone up, it is suddenly on a piece of medical equipment.
Answer: The Hulk is a giant brute who smashes everything in his path when he is angry. In Ang Lee's "Hulk," General Ross, played by Sam Elliot, explains it to his daughter.
