Plot hole: During the nova scene, everyone is tying down the sails after securing themselves with lifelines to the mast. Jim and Silver are on the front and Silver is knocked off. Jim is then all dramatic and runs to grab Silver's lifeline which seems to be coming from above, and pulls Silver up like a pulley. How come? The lifelines were attached to the mast, so Jim's action is pointless... even if he could do it, because a shot later both lifelines are streaming right to the mast, leaving no room for a pulley of any sort.
Plot hole: When Karen is at Moselle's apartment looking for Snoopy, we overhear Kenneth on the phone talking about some boxers who are going to fight. The first thing we hear is him clarifying that the fights were at the State Theater. The fights are always at the State Theater and they always go there to watch them, so it makes no sense for him to have said that, other than to subtly benefit the plot.
Plot hole: When John retrieves the mail from the postman, Iris dashes outside. Less than 10 seconds after she closes the door, a car is heard, off-camera, honking a horn. Wouldn't John have found Iris so soon after that noise is heard? She doesn't seem to have enough time to allow for a search for her.
Plot hole: When Jo is getting to walk down the aisle with Queen Clarisse, he hands Shades his top hat and then pops his ear piece right off, in a split second, and puts it in the top hat. In the previous scenes, Princess Mia has Lionel's ear piece stretched from the back of his neck, across his jaw and around his chin and then stretched to her ear but it hasn't popped out, while Queen Clarisse jerks Charlotte with her when she goes to listen to Princess Mia.
Plot hole: Junuh gets the lowest score on the 17th hole in the final round, which puts all the players at 'even'. It should therefore have been his honour 18th tee. He actually tees off last, which would indicate that Jones and Hagan had bettered (or at least matched) his score on the 17th.
Plot hole: The first time David werewolfizes, he's reading a book in the brightly lit apartment. Exterior shots of the full moon show it's nighttime out, so the lights inside the apartment must be on. But when Dr. Hirsch calls to check on him, the shot is of the phone ringing, unanswered, in the completely darkened apartment. That's considerate, David. Even as a werewolf, he must have run around turning lights off before going on his rampage.
Plot hole: They all drop their backpacks and bags 3/4 mile down into the hole before climbing by rope into the caverns to begin their journey. Later in the movie, they are all sitting deep in the caverns complaining about the lack of water supply. Suddenly the long-haired guy pulls out a large glass bottle of gin, completely intact and they all drink from it. There is no way his pack could have fallen 3/4 mile onto a hard surface without that bottle breaking.
Plot hole: If Tori (Jessica Pare) has fears of being discovered that she's a lesbian and involved with Paulie (Piper Perabo), why would they be making out in the schoolyard and hanging all over each other in the gazebo?
Plot hole: Mr. Foyt spies on J.J. and Victor to find out more about the Cannonball, yet fails to recognize them when they stop to pick him up.
Plot hole: When Farley is preparing to rescue Simon by towing him up with the rope attached to his van, he drops his "cigarette" into his crotch, causing him to floor the gas pedal. His back wheels begin to spin. This is impossible because the vehicle is still in Park. There is even a camera shot of the "PRNDL" proving this. I guess this goof is employed by the filmmaker to increase the dramatic effect of him subsequently slamming the Dodge into drive a second later and careening through the fence. (01:07:35)
Plot hole: When Ralls runs the Witch onto the reef, he is at the helm. As she strikes bow on, the wheel spins madly for no reason, as the tiller ropes would not have been affected by the collision.
Plot hole: Dora is sleeping after being taken to the hospital, she wakes up in Paul's bed. Assuming, she recognizes the place as the one where the fundraiser/party is held, how can she know that it was Paul's bed and that he lived there? Furthermore, she also seems to know that she was in the hospital, and that Paul was the one who took her. Seeing the exchange of dialouge between Paul and the doctor, and Paul and her, there was no way she could have known that information prior to her waking up.
Plot hole: Katherine (Kirstie Alley) the tooth fairy is instructed by Rodgers (Lynn Redgrave) that she can only go out at night, otherwise she stays in an apartment in Limbo to get her assignments. She is given names all over the world. There is always a part of the world that is in nighttime. She should always be working and never at Limbo.
Plot hole: The scene where Andie comes over for dinner and moves a bunch of frilly stuff into the bathroom, happens at least one day before she comes over with the wedding album she made. In that scene, Ben goes into the bathroom to splash water on his face and discovers the pink hand towel and other stuff - that means he would not have gone into his bathroom for at least a day, or two, since she put the stuff in there, or he would have noticed it sooner.
Plot hole: The boys who chase Sarah pick up large stones from a carefully tended lawn, and they find them between the leaves without a bit of searching around. (01:15:45)
Plot hole: The hot air balloon carries Fogg and friends quite a distance, but where is the heat source?
Plot hole: Lucy has been painting pictures of Henry since she moved into the institute. But she passes him at the zoo and doesn't recognize him.
Plot hole: How did Dolittle manage to rescue an incredibly heavy bear from drowning? He must be unbelievably strong to be able to drag a bear of that weight. (00:35:25)
