Audio problem: In the scene when Josh (as Tom Hanks) comes back to his house to talk with his Mother for the first time since becoming "big", she starts screaming and backs away from him. She backs into the piano she says "Go away, go away." but her lips don't move at all. (00:16:45)
Audio problem: When Josh is about to be interviewed, a woman says "Personnel director would like to see you now" but she's not mouthing the lines.
Answer: Paul (John Heard) tells Josh that the serve has to cross the yellow line. When Josh calls the ball short, Paul is basically trying to cheat and claims he never said the ball has to cross the line. Although I'm trying to figure out what racquet sport their playing. It looks like they're playing on a handball court, but the racquet sports I know, the ball has to cross the short line (the yellow line in "Big") on the serve but you also serve from a service area where you have to stand in front of the short line, which they don't do.
