Best family movie mistake pictures of 2004
Visible crew/equipment: When Hermione and Harry go back in time, they duck and hide from Malfoy (after being punched) and his friends as they leave. The rectangular outline of a power pack (battery pack for hidden cordless mic) is visible at her lower back, under her pink jacket. It is visible in a few shots, including when they are at the pumpkin patch. The outline of Harry's power pack at his back is visible as well, as he bows to Buckbeak at the pumpkin patch, when they rescue him.
Continuity mistake: When Odie comes out on the porch to keep Garfield company, his collar and tags are visible; even more so when he attempts to get back in. But when the shot pulls away to show Odie alone on the steps (before running off after the scooter), his collar is gone. Part of the plot hinges on Jon trying to find Odie, who wasn't wearing his tags.
Continuity mistake: As Barrie (Depp) and Frohman (Hoffman) are sitting in the theatre shortly after Barrie seeing all the sets being removed from the theatre, there are a number of guys removing what look like set doors. The first two guys that walk behind Barrie make a large distance between seeing them and walking down the hall. A few seconds later two more guys just walk past the back of Barrie and in the very next shot they have disappeared.
