Audio problem: Just before Aunt May does her hero speech she tells Peter that he 'Did a very brave thing, telling me, and I'm proud'. There is a pause between each clause of the sentence and the 'Telling me' line is obviously dubbed, the shot is from behind but the sound of the line is different.
Audio problem: When Aunt May gives Peter his birthday money, before she says, "Can you believe that it's two years next month since he was taken?", we see her from the side, and the motion of her jaw shows that her lips are moving before she speaks. When she says, "Were I to face the one responsible.", there's another shot of her from the side, and as she continues, ".for what happened", her jaw doesn't move at all. In the same shot, when she says, "Oh, I don't know what I'd do", once again the motion of her jaw show that her lips are moving before she speaks.
