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)
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)
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)
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)
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: When Doc Samson kicks through the cab wall of the vehicle that is transporting the Hulk, he leaves a hole roughly the size of his leg, and the appearance of the damage suggests he kicked through metal. A couple of shots later, the hole is large enough for a person to fit through, and the appearance of the damage suggests it is now broken glass. (00:19:56)
Continuity mistake: When She-Hulk deflects the potted plant that Ogress throws at her, she gets dirt in her hair and on her arms and legs. When the shot changes, her hair and limbs are suddenly clean. (00:10:10 - 00:10:40)
Continuity mistake: Ogress is depicted as having five teeth. Two on top, and three on bottom. When she is saying to the Thing "Your chivalry is wasted on me," the bottom-middle tooth disappears. (00:08:50)
Darkness and Light: Part 1 - S1-E11
Continuity mistake: When Rick Jones comes to tell Betty that S.H.I.E.L.D. has taken the Hulk, he is standing by the door, and she is standing at the foot of Banner's bed. When the shot changes, they are both suddenly standing in front of a large window. (00:19:05)
Darkness and Light: Part 1 - S1-E11
Continuity mistake: When the S.H.I.E.L.D convoy is taking Hulk away, they are shown driving down a desert road, with large rocks on the shoulder. When the shot changes, the road is suddenly adorned with street lights. (00:19:43)
Continuity mistake: When the government employee hands Betty the federal document, the federal seal disappears. (00:01:58)
Continuity mistake: When She-Hulk is talking to Hulk by the torch on the Statue of Liberty, she is standing directly in front of the Thing. When the shot changes, she is instantly a few feet away from the Thing. (00:19:57)
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)
Factual error: The opening shot of the Statue of Liberty shows the statue's left arm to be raised too high. The real statue has its left arm close to its midsection, whereas the statue depicted here has its arm nearly raised to shoulder level. (00:00:01)
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)
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)
Continuity mistake: When Ghost Rider tracks down the Hulk at the salvage yard, he pulls his motorcycle right up to within a couple feet of the fence. When Rick Jones pulls up perpendicular to Ghost Rider, one shot over Ghost Rider's shoulder shows pavement behind Rick instead of a fence. A couple of shots later, the fence is directly behind Rick. Another couple of shots later, Ghost Rider is shown from the back saying "An innocent victim shall suffer" and he is suddenly facing a group of buildings instead of the salvage yard. All remaining shots in the scene place Rick and Ghost Rider back by the fence.
Man to Man, Beast to Beast - S1-E6
Continuity mistake: When Taylor discovers Sasquatch's footprints in the snow, they have no toe prints. When Taylor's father finds the same footprints, they now have toe prints.
Helping Hands, Iron Fist - S1-E4
Continuity mistake: When Rick Jones is hanging on to the containment unit that the Hulk is trapped inside, at one point the Iron Man gauntlet that he borrowed switches from his right hand to his left.
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.
