Continuity mistake: When Happy is trying out for the hockey team, he sends a slapshot in front of the coaches and it breaks the glass. In the next shot the glass is intact. (00:04:07)
Revealing mistake: When Happy tosses the IRS agent out of Grandma Gilmore's window, he falls down the steps outside and it is blatantly obvious that he is wearing kneepads under his suit pants. (00:09:06)
Continuity mistake: Near the start we see Happy dropping off his Grandmother at a rest home. When they arrive Happy is driving on a walkway through the compound. Odd place to be driving don't you think? (00:09:08)
Continuity mistake: When Happy is taking grandma Gilmore to the nursing home you can see a picture of grandma on the rear view mirror. When the lady jumps on the car and Happy throws food on her you can see the picture of grandma Gilmore is no longer there. (00:09:27)
Continuity mistake: When Happy and his Grandmother arrive at the nursing home, Happy puts his Grandmother's suitcase under the bed. In the next shot it's not there anymore. (00:09:45)
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)
Suggested correction: The kid plugged it in off-camera.
Continuity mistake: In the scene where Happy is talking to Chubbs in the parking lot, when Happy hits Chubbs' hand off, you can see that Chubbs is throwing his hand rather than getting it hit off by Happy's hockey stick. You may have to watch in slow motion. (00:16:46)
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)
Other mistake: When Shooter is telling Happy to meet him and the other pros at the 9th green, everyone in the background is talking among themselves, then suddenly are closer and staring at them. (00:31:47)
Continuity mistake: When Happy autographs the girl's chest and then the film cuts as he autographs the old lady's chest his name on the girl's chest is different to how he wrote it. (00:45:57)
Continuity mistake: When Virginia and Happy are dancing on the skating rink, when the camera is zoomed in on them, Virginia is holding the hockey stick. Then when the camera zooms out, look closely and you can see she isn't holding the stick. (00:52:50)
Revealing mistake: When Happy and Bob are rolling down the hill, you can see from the face that it's Bob Barker's stunt double. (00:57:05)
Continuity mistake: When Happy pleads with Chubbs to take him for lessons, he shakes Chubbs' hand. He pulls off a few fingers, but not his ring finger. When the shot changes to behind Chubbs, you can see that his ring finger is not there. (01:03:35)
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)
Revealing mistake: When the car hits Happy you can see the flack jacket used to perform this stunt underneath his shirt. (01:14:07)
Continuity mistake: During the segment where the V.W. bug hits the media tower there are a few inconsistencies. First off when the bug hits the tower the pole wraps around the front end staying intact. In the next shot it shows the pole is broken and sitting on the hood. Then there's a shot where it shows a guy laying on the ground and the bug in the background. Now the bug has backed up about 4 feet and the pole is now not broken and only bent. (01:14:18)
Continuity mistake: When the V.W. bug hits the media tower the front area of the car is already charred before it catches fire. (01:14:19)
Plot hole: In the final tournament when Happy is stuck in the rough, he swings five times. Assuming he hit his drive into the rough and hit an AMAZING shot from the edge of the water into the hole, he still could do no better than a seven on the hole. Happy only lost one stroke on the hole. (01:16:50)
Continuity mistake: The point in the movie when Shooter is mad about the beach ball being thrown on the green, watch his ball. It changes its position on the green from one view to another. (01:20:12)
Continuity mistake: At the 18th hole when the television tower collapses you can see a man in an orange t-shirt and jeans jump off onto the floor. However in the next shot (it is quite quick so you might have to watch carefully) the same man is just jumping off and is still in the air rather than on the floor. (01:23:35)
