Revealing mistake: When Carl is caddying for the priest during the bad weather, the wind is so strong that it is almost blowing them over but the trees are not moving in the background.
Other mistake: During the dinner party scene, Carl is going gopher hunting. The shot of him approaching the tree shows it's daylight in the background, when the previous shot showed it very very dark out.
Continuity mistake: When Lacy visits Ty at his house, Ty offers her a drink. As he leaves the bar area he has the Perrier bottle and bottle opener in his left hand and the glass with lemon in his right. In the next shot, he's shown handing the glass to Lacy with his left hand and the Perrier bottle and opener is now in his right hand.
Continuity mistake: When Al Cvervik is walks into the golf club, the Judge is standing next to the counter, but when Al says, "it looks good on you though," the judge is about three feet away from the counter. Also, a hat appears on the counter from nowhere, because the judge hangs his up, and Al puts his back on the statue. (00:17:45)
Continuity mistake: At the dinner party, when Ty makes his appearance he walks toward Al Czervick and greets his guests. Watch closely in the background, Lacey is looking in Ty's direction with two guys on her right, but in the following closeup a woman in a red dress has suddenly appeared. (00:32:10)
Continuity mistake: Early in the film, when Ted Knight arrives at the final hole and Rodney calls out "1000 bucks you miss the putt", we initially watch Ted line up the putt and it is only about 2 feet long (shoulder width). The shadow from his head is only a few inches from the hole. After getting flustered by Rodney's bet, Ted again sets up over the ball, and suddenly the putt has doubled in length. More importantly, the sky has changed from mostly sunny to considerably cloudy and the shadow from his head is at least 4 feet from the hole.
Continuity mistake: At the dinner party, when Spaulding gulps down some half-finished drinks left on a table, his unknotted bow-tie is hanging on the left side of his neck. He nearly gags on the last drink and quickly exits the room. In the next shot, outside the restaurant, his unknotted bow-tie is hanging on the right side of his neck. (00:35:25)
Revealing mistake: During the opening credits, the gopher is tunneling under the grass and plowing it up as he goes. In one of these shots, the path the gopher will take can be seen before he even gets there. The darker special-effects grass that the underground "gopher" will tear up is obvious. (00:00:35)
Continuity mistake: When Danny is putting his money in the college fund jar, you see the Cheerios box straight, but when it cuts away then cuts back, you see the box moved at an angle. (00:02:55)
