Revealing mistake: When Hulk rips the turret off the tank and swings it around in the desert has a solid base. This is correct for a model but not for a real tank which has a hollow turret for the tank captain to stand up from the bottom of the tank through the turret and look out the top.

Harper: Bruce! Big day. Did you sleep? I didn't sleep.
Bruce Banner: Slept okay. Is Betty here?
Harper: She's around. I really got to say, seeing you in that styling headwear.
Bruce Banner: You're implying something about my helmet?
Harper: You look like a massive nerd, even around other scientists. Can just I ask? Were you wearing the helmet while she dumped you?
Bruce Banner: See? It protects my very important brain, Harper. Go prep the samples.
Trivia: The face of The Hulk is a computer generated image of Erik Bana, Jennifer Connelly, and director Ang Lee combined into one.
Question: Does Bruce Banner remember anything he does when he becomes the Hulk?
Answer: There are varying interpretations of Bruce's memory in the comics. The most common one is that Bruce has vague memories of what happens while he is the Hulk (i.e. fear, hunger, images), but because the Hulk's brain is less "evolved" he can't remember specific information, like where he went or what he did. The converse is also true: The Hulk has vague memories of Bruce's life as well...he recognizes people that Bruce knows but doesn't know anything about them.
