Helping Hands, Iron Fist - S1-E4
Audio problem: When the S.H.I.E.L.D. helicopters land at Stark Industries, you can hear their rotors slow to a stop, but the animation still shows them to still be spinning.
Audio problem: When General Ross interrupts Gabe Jones by saying "Will be under my exclusive command," his mouth is not moving for the word "exclusive."
Helping Hands, Iron Fist - S1-E4
Audio problem: When Gabe Jones has his back to the camera and is telling Ross where on the map that Hulk was going, his jaw is not moving at all.
Audio problem: When General Ross is saying to Major Talbot "If Nick Fury thinks he can just..." his mouth isn't moving.
Continuity mistake: When Hulk jumps up onto Talbot's helicopter, it changes color from an army green to blue.
Audio problem: When Hulk is saying "Hulk smash! Hulk bash!", his teeth are clenched.
The Return of the Beast: Part 2 - S1-E2
Continuity mistake: When the Leader is preparing to force Banner to transform into the Hulk, he shoots Gargoyle in the left shoulder with a blaster for being insolent, which leaves a hole in the corresponding area of his clothing. Moments later, the hole has disappeared.
The Return of the Beast: Part 1 - S1-E1
Continuity mistake: When General Ross is warning Banner that he is not bulletproof, an armed guard is flanked on either side of Banner. When the shot changes, the guard on Banner's left had suddenly moved several feet away.
The Return of the Beast: Part 1 - S1-E1
Continuity mistake: When Rick is telling his boss that he needs to leave work to help out a friend in a jam, he is standing next to the payphone, and when the shot changes, he is already several feet away sitting on his motorcycle and putting his helmet on.
The Return of the Beast: Part 1 - S1-E1
Audio problem: When Rick answers the payphone, his mouth isn't moving when he says "Ed's Garage."
The Return of the Beast: Part 1 - S1-E1
Continuity mistake: When the Hulk is trapped inside the containment unit and Betty calms him down, once he has reverted back to Bruce Banner, his hair is shown being blonde instead of brown.
The Return of the Beast: Part 1 - S1-E1
Audio problem: When the soldier is telling Talbot what Banner is doing with the power station, the soldier's mouth and jaw areas are not moving when his back is towards the camera.
The Return of the Beast: Part 1 - S1-E1
Continuity mistake: When General Ross is talking to Betty about the danger the Hulk presents to the world, the distance between them differs depending on the shot. One shot shows them standing close enough to hug each other, the next shot shows them instantly at arms' length apart.
Other mistake: This show is in the same continuity as the Fantastic Four series from around the same time. However, in Fantastic Four, Dr. Doom has a German accent, and in this episode, he has a slight British accent.
Other mistake: When Betty is going over the plans to infiltrate Sea-Base, she mentions they have to go ten floors down. When we see the base, it is nowhere near tall enough to be ten floors.
Factual error: When Bruce is tying the rope through the handles of the magnetic devices to prevent falling onto the laser beams, he only loops the rope through the one on the left, he doesn't tie a knot. The moment he started hanging onto the rope, his weight should have pulled it through the handle.
Factual error: Dr. Doom traps Hulk on an asteroid and sends it hurtling towards the sun, which it reaches in a matter of minutes. The sun is around 93 million miles from the Earth. Even if the asteroid was traveling at one million mph, it would still take nearly 4 days to reach the sun, not merely a few minutes. The same mistake applies for Hulk returning to Earth within a few minutes.
Factual error: When She-Hulk spikes the volleyball into the sand, it leaves a hole. Sand is so densely packed that at best, this would have left a small crater. (00:00:25)
Other mistake: When the Leader and his minions are escaping to the rooftop, the bomb detonator says there are only 30 seconds left. After Leader escapes and Hulk goes back into the building to get the bomb, the detonator says 10 seconds remain. While there is an argument to be made in movies and television not being strict with real time, in this instance, far too much happened onscreen for only 20 seconds to have passed. The heroes confronted the villains, one villain tried to talk a hero into coming with them, the police arrive on the scene, a battle happens on the rooftop, the villains escape with the police in pursuit, etc.
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.
