Continuity mistake: In Fletcher's office, Fletcher is berating his son about a pencil. As he does so, he's fully beside his son at face level. After the camera changes angles, there's a guy in a white suit sitting far enough away that Fletcher could be between them. Another moment later, the man is shoulder to shoulder with Fletcher's son.
Continuity mistake: When George is talking about the station's programming, his hands are below the desk top, out of sight. When the angle changes, his right hand is suddenly at chest height.
Continuity mistake: At the end of the telethon when they are just about to make 75,000 dollars, Al puts the money in the limo guy's window. Look at the sign showing the dollar amount they are at. It shows 75,000 well in advance of them pulling it down (which happens in the next shot). (01:26:25)
