Continuity mistake: In the beginning of the movie he is not taken onto the hockey team. After he is hustling at the driving range he goes to toughen up. As he is toughening up, Chubbs unplugs the machine. The kid tries it, but he never plugged it back in and the machine still manages to work. (00:15:10)
Continuity mistake: In the final round, when Happy and Shooter McGavin are about to tee off on the first hole, they show a picture of the 18th green with the Volkswagen Beetle already crashed into the TV tower. However, this doesn't happen until Happy gets hit by the car later in the game. (01:09:25)
Continuity mistake: During the last tournament scene at the beginning of it look at the Media Tower the crashed V.W. is already there but that part has not happened yet. (01:09:20)
Continuity mistake: The exact same shots of the golf ball sailing through the air are used two or three times, especially during the last golf tournament.
Continuity mistake: When Happy is about to putt and the tower starts to fall, his caddy is behind him. In the next wide-angle shot, his caddy is in front of him, or at least between Happy and the hole, where before Happy was between him and the hole. A couple of shots later, when Virginia runs up to Happy, the caddy is back to his old position again.
Continuity mistake: Happy and his new caddy are discussing the shape of the green and the caddy says the green is slanted to the left. When Happy tells him it only seems that way because he's missing a shoe, the caddy is standing with his feet shoulder-width apart. When the camera cuts to the close-up of his feet, they're together, yet the caddy didn't move.
Continuity mistake: In the beginning when Happy first meets Chubbs, Happy backs his car into a couple of trash cans after Chubbs mentions big bucks. When Happy backs into the trash cans and stops he leans out the open window with his elbow over the side; you can see this through the back window. But when it shows a close up of Happy in the next shot, he's sitting calmly in the car with both arms in his lap. (00:17:20)
Continuity mistake: Near the end of the movie during the final round of golf Happy is wearing a tee-shirt under a button shirt that is open. All through the round the tee-shirt goes from a Subway shirt to a white shirt with a brown strip across the chest. It is much more noticeable during the last putt. He has the stripe shirt while putting then when he makes it and every one rushes to him it is the Subway tee-shirt.
