Continuity mistake: At the opening of the film when Billy is in the pool, after he puts the suntan lotion on and realises that it is nudey magazine day, he begins to wade out of the pool. In the side on shot he is holding a wineglass, but a split second later the wineglass has vanished.
Continuity mistake: When Billy and the people who work at the mansion are playing kickball, after he runs to second base, the sign in the background says something about Billy's team always winning. But when the camera cuts to the 2 nurses on first base the sign is in mid-stroke of changing into something entirely different. And the camera change is too quick for it to have done that automatically.
Continuity mistake: During the singing number where Billy decides to go back to school, Billy, Veronica, the kids, and the clown are on the front lawn. Billy is standing on Veronica's left. However, in a wide shot when they start "Do you have any more gum?" Billy is on Veronica's right.
Continuity mistake: At the party after the piñata is broken the amount of candies on the floor changes between shots.
Continuity mistake: The sunblock cream on Billy's chest disappears when he gets to the house.
