Grumpier Old Men

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. (01:07:10)

Continuity mistake: Jack Lemmon puts the cat in Walter's truck. We see a close up of the cat's paws scratching holes in the car seat. A long shot shows the cat picking at the seat again, but there are no holes in the seat anymore.
