Continuity: When Molly comes for her first golf lesson, Costner takes the last bite of his hot dog. In the next scene, he still has some of the hotdog left.

Continuity: During the press conference at the U.S. Open where Roy begins to list the companies who are sponsoring him, he says that one of them is "Woody's Smokehouse" when the patch on his jacket says "Wally's Smokehouse".

Factual error: When Roy is giving Molly her first golf lesson, she is using a driver, the hardest club to hit. Any golf professional would have a student start with a short iron.

Revealing: In the scene where Romeo and Roy snap all the clubs other than the 7-iron, Roy drops his golf ball onto the grass. However, when he hits the ball, a white tee can be seen travelling up towards the top left of the screen. The tee can easily be seen but is much clearer in slow motion.

Continuity: When Molly goes to see Roy when he is wearing all that golfing equipment, when they go to sit down at the table Roy can be seen taking off the blue arm band and when the camera pans back for a wider shot, he is seen taking it off again.
