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 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)
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)
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.
