Continuity mistake: In a scene where Maria and Max are talking inside the restaurant, right before they are about to leave, the shot changes from her having her purse on her shoulder, to it not being there.
Revealing mistake: When "Pop" dies, you can tell he is still breathing, especially if you fast forward the scene. He is just doing it very slowly, but you can see his chest move up and down.
Revealing mistake: When Catfish Hunter swims away at the end, you can see the shadow of a crew-member or some sort of device operating the puppet fish, under the water.
Revealing mistake: When Catfish Hunter jumps out of the water towards the beginning of the movie, you can see that the splash of him landing in the water is actually in front of where he actually lands.
Continuity mistake: When Grandpa is singing a lullaby to Ally, her hair is across her forehead. In the next shot of her sleeping, her hair is neatly tucked behind her ear.
Continuity mistake: In the scene at the new restaurant, every time they show the case of wine bottles, one bottle is in a different position. One time it is cockeyed in the case and the next it is correctly in the case.
Revealing mistake: When the kid in the store keeps knocking down the bottles and cans, you can see he barely grazes them, and yet they all fly off the shelves.
Continuity mistake: In the scene where Sophia Loren leaves the bar, Ann-Margaret sees her and call her Vivian. Sophia's character name is Maria. You can see this on the VHS only because it is corrected on the DVD.
Continuity mistake: While sitting on the bench, near the lake, when Grandpa is telling John about out living everyone by eating bacon and smoking everyday, he has a cigarette in his left hand and a beer in his right hand. After a few minutes, when it switches back and forth from Grandpa to John, the cigarette and beer switch hands and then back again, between shots.
Character mistake: When Lucky the dog is chasing Slick the cat, into John and Ariel Gustafson's house, Ariel yells out her husband's name, she actually yells out the actor's real name Jack instead of John, the character's name. Pay close attention, it could be easily missed.
Continuity mistake: When Jack & Walter drive to the fishing spot instead of the wedding, the exterior shots of the car show the Dodge Polara as a 4-door pillarless hardtop. When the interior of the car is shown, it is a four-door sedan, showing the thick pillar seen behind each man as they converse. As they speed back to the wedding, the four-door sedan now appears in a couple of exterior shots, and now the hardtop is used during interior shots of both men through the windshield.
Continuity mistake: When Max is eating his mac and cheese it changes camera shots rapidly. In one shot he's got some mac and cheese on his fork, in the next shot it's gone and the fork is clean. It does that a couple of times.
Audio problem: The scene where Daryl Hannah and Kevin Pollack are arguing in the middle of the crowd doing the chicken dance, the timing of the music is not matched with where the crowd is in the dance.
