Continuity mistake: When Betty is walking through the infirmary, she is walking past a bedridden man to his left. After he reaches out and grabs her by the arm, the shot changes and she is suddenly on his right.
Audio problem: When the government employee is saying "You are hereby ordered to accompany me to Detroit," his mouth and jaw are completely motionless.
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 the Thing is crumpling the flyer between his hands, the flyer alternates between being white and the same orange color as the Thing.
Continuity mistake: When the cage is dropped over the Thing, you can see it is a big solid rock slab on top of wooden bars. When the shot changes, the inside of the cage somehow fills up with bananas, even though there was nowhere for them to drop directly into the cage from.
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)
Continuity mistake: When Hulk says "Thing? Hulk enemy," he raises his right fist while standing face-front towards She-Hulk. When the shot changes, his fist is immediately out of shot and he is now standing shoulder to shoulder with She-Hulk.
Revealing mistake: When Hulk jumps out of the river towards the New York skyline, he disappears into thin air.
Other mistake: When the forklift driver gets distracted by She-Hulk and crashes into the stack of metal vials full of flammable liquid, Bruce and She-Hulk don't hear any of the commotion until the explosion happens, even though they are only a few yards away. The crash and the falling metal vials should have been loud enough to alert them.
Continuity mistake: When Bruce and She-Hulk are hitchhiking, the sign for New York behind them changes size and lettering. When it is first shown, it is significantly taller than both of them with the lettering reading "NeW York" (sic) in a thin and long font type. When the shot changes, the sign is much shorter and the lettering now reads as "NEW York" in a more block-lettering style.
Factual error: The opening shot of this episode incorrectly depicts the Lincoln Memorial Reflecting Pool to be located between the Washington Monument and the U.S. Capitol building. In reality, the reflecting pool is located between the Lincoln Memorial and the World War II Memorial, with the Washington Monument roughly 1/5 of a mile east of the World War II Memorial, and the U.S. Capitol nearly a mile and a half east of the Washington Monument.
Man to Man, Beast to Beast - S1-E6
Continuity mistake: When Dr. Langkowski presses the play button on Banner's tape recorder, he is pressing on the right side of it. When the shot changes, the buttons are now on the left side of the recorder.
Man to Man, Beast to Beast - S1-E6
Deliberate mistake: When Bruce Banner is crawling away from the town that Hulk attacked, he passes out in the snow and is rescued by Sasquatch/Walter Langkowski. When he awakens in Langkowski's lab, he is wearing his usual outfit. Since he was only wearing tattered pants when he passed out, that means his clothes were given to him by Langkowski, which is extremely unlikely since the two hadn't seen each other in a long time and Langkowski didn't even know Bruce was looking for him.
Continuity mistake: When Ghost Rider crashes his motorcycle out of the building with Talbot in tow, he is holding Talbot around his midsection. When the shot changes to them in free fall, he is gripping Talbot by his collar. When they land on the street, he is back to holding him around his midsection.
Continuity mistake: When the helicopter is put in hover position for Talbot to shoot Hulk with the tranquilizer weapon, you can see that the pilot seat is unoccupied. When the shot changes, Talbot is suddenly in the seat.
Revealing mistake: When the Hulk is sitting on the edge of a building, Talbot suddenly appears in a helicopter to ambush him. If you watch closely, you can see the helicopter originates from behind Hulk instead of rising up from behind the building.
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.
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.
