Helping Hands, Iron Fist - S1-E4
Factual error: When Bruce Banner sees the Hollywood sign reflected in the puddle of water, the reflection is backwards.
The Return of the Beast: Part 1 - S1-E1
Factual error: When the Hulk jumps up and grabs on to the tail of the helicopter, he is somehow able to hang on to the tail while spinning the helicopter in a circle. Helicopters require a certain weight distribution in order to maintain stabilized flight. Someone of the Hulk's size and strength wouldn't be able to just hang on to the tail and spin the helicopter. He instead would bring the helicopter crashing down.
Factual error: She-Hulk stops the runaway truck by holding onto the back of it and letting her feet drag on the asphalt. Afterwards, her high heels are still intact. The friction from stopping the truck would have destroyed her shoes within seconds. (00:06:00)
Factual error: When the Dark Hulk is attacking the city and destroys a helicopter, the occupants can be seen with their parachutes already deployed immediately after the helicopter has exploded. Not only would they not have had enough time to already be parachuting to safety, but given that the helicopter was only a few stories high in the air, they wouldn't have had time to safely deploy their parachutes in the first place.
Factual error: She-Hulk's license plate reads "GAMMA-GRL." She's from Washington DC and now resides in New Mexico. Both places have a limit of seven characters on a license plate. It can't be a vanity plate either, because both places also require front and rear plates.
Factual error: When Hulk throws Abomination over the post office, the United States flag has only ten stripes, five red and five white. The U.S. flag has 13 stripes, seven red and six white. (00:04:50)
Factual error: When Hulk lands on top of Mount Rushmore, Teddy Roosevelt's glasses are missing.
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.
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)
Factual error: When She-Hulk loses her grip on the elevator cable, she catches onto the structure on the walls, but Betty loses her grip and falls several floors before She-Hulk can fall after her. A couple of shots later, She-Hulk has already caught up with Betty, even though there wouldn't be enough distance for She-Hulk to have reached terminal velocity to catch up with Betty.
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)
Factual error: When Hulk throws the Humvee at the helicopter, the pilot bails just before it explodes and manages to deploy his parachute. The helicopter was hovering roughly 30 feet above some buildings. That's not nearly enough distance for the pilot to have deployed his parachute before he fell onto the roof of one of the buildings.
Man to Man, Beast to Beast - S1-E6
Factual error: Hulk rescues Taylor from the icy waters, but Taylor shows no signs of hypothermia afterwards. He should be shivering profusely. Hulk naively tries to cuddle the boy and blow on him, but even if that had the ability to warm him up a little, his wet clothes would still be an issue.
Factual error: The moon in the night sky in this episode is far too large.
The Return of the Beast: Part 2 - S1-E2
Factual error: When Betty's humvee breaks down in the middle of the desert, she gets out and steps over a scorpion. The scorpion is shown to have 10 legs (4 standard legs and 2 pincers). Scorpions have 8 legs.
Suggested correction: A scorpion's pedipalps (their pincers) are not legs. Scorpions and other arachnids have 8 legs and 2 pedipalps.
