Cats & Dogs (2001) - 31 mistakes
Directed by Lawrence Guterman, starring Alec Baldwin, Elizabeth Perkins, Jeff Goldblum, Miriam Margolyes, Tobey Maguire (add more)
Continuity: In the scene in the flocking factory when Jeff Goldblum's character is being confronted by the cat leader (Mr. Tinkles) another cat (Calico) is on Goldblum's shoulder. When the shot changes to an angle behind Goldblum, Calico disappears only to immediately reappear when the shot changes back to the angle facing Goldblum.
Continuity: The lawn goes from established grass to freshly laid sod back to established grass. In the daylight scenes you can tell that the grass is growing, probably 4 inches tall, not mowed recently. During one of the night scenes about half way through the movie, you can see that the grass is kind of sickly looking and you can also see the lines around the strips of sod. The next day while the kid is doing his soccer stuff, the grass is back to green and uncut.
