Plot hole: If Happy Chapman is supposed to be allergic to cats how come he doesn't sneeze whenever he is around Garfield?
Garfield: The Movie (2004)
1 plot hole - chronological order
Directed by: Peter Hewitt
Starring: Bill Murray, Jennifer Love Hewitt, Breckin Meyer, Stephen Tobolowsky
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.
Trivia: Bill Murray agreed to be in the film without reading the full script upon seeing the name "Joel Cohen" listed as a writer. It turns out he thought he was signing onto a film co-written by "Joel Coen" of the Coen Brothers fame. It wasn't until he began recording his lines sometime later that he realised his mistake.
