Audio problem: During the scene where Talbot approaches Betty by the elevator, it splits and in doing so the top left screen does not speak, but the bottom right does, and they are supposedly "Sync"ed.
Audio problem: During the scene where Bruce's father is giving him the green dinosaur toy and the monkey toy and suggests making them have a fight, the boy "Roars" but his lips don't move at all, in fact his mouth is shut.
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.
