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: 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: 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)
Other mistake: When Happy hits the ball in the alligators mouth, he is on the complete other side of the lake where the gator is located, and there is a crowd of people blocking his view, but somehow he can still see through the people and over the lake, to notice the gator taking his ball.
Revealing mistake: In at least one scene, you can see the ruts that the filmmakers made in the greens to make Happy's putts go where they wanted them to.
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)
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)
Revealing mistake: In the scene where the Volkswagen is driving on the golf course to run over Happy, you can see tracks in the ground where the car had already been.
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: The exact same shots of the golf ball sailing through the air are used two or three times, especially during the last golf tournament.
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 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)
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: At the final golf tournament, Happy's grandmother tells him she just wants him to be happy. In one shot, both her hands are up towards Happy, in the next shot only her left arm is up, and in the next shot both hands are up again.
Continuity mistake: When the alligator takes off with Happy's golf ball in his mouth, he takes off and slides down into the pond where he goes through a patch of water-lilies. When Happy dives in the water after the alligator there are no water-lilies.
Continuity mistake: After Happy gets hit by the car he's lying on the ground and you can see he's only wearing the Subway shirt. But when he tees off near the end he's wearing a shirt over the subway one.
Suggested correction: He's wearing the orange button-down shirt the whole time.
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: 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: 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: 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)
