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: During the scene in the final round where Roy and David hit their balls onto a green, there are a couple of mistakes (one mistake has already been noted in this scene - the mistake where Roy is swinging his putter from side to side etc). Firstly, as they all walk up to the green, Roy's ball (which should be quite close to the hole) is not on the green. Secondly, when Dave misses his putt, look at Romeo. He is standing to the right of Roy, but in the immediate next shot he is on Roy's left.
