Plot hole: The sheer distances Kevin covers on foot in one night are outrageous. Between 9pm and midnight he walks from Carnegie Hall to the children's hospital, to 95th street, back to the toy store carrying a large paint can and a large 2x4 (street signs here put it around 59th and 5th), back up to 95th, then all the way back to midtown, to Rockefeller Plaza. One way from W 95th street to around E 59th and 5th Ave. is at least an hour on foot for an adult, he does this 4 times between 9pm and midnight, once while carrying a 2x4 and paint can, once while being chased by 2 adults, and he still has time to set up a house full of traps.
Plot hole: To rig blackjack card shuffling machines to make the dealer bust and everyone else get 20 or 21, its success would depend entirely on knowing the exact number of people at the table at that time. Perhaps the filmmaker is assuming all seats at the high-stakes blackjack tables would always be filled during a "soft" opening, but that seems extremely unlikely.
Plot hole: Bridget is wearing a shirt from Mrs. Darcy (the line about Mark's mother's taste in shirts, which is said while showing BOTH shirts, definitely suggests that - her idea of cuteness for a couple, I guess), which doesn't make sense because the first movie ended on New Year's Eve (we know that because Shazzer and the rest of the gang were taking Bridget to Paris that night to celebrate the New Year, but Bridget ended up with Mark - unless the movie take place a year later, which it doesn't, it takes place the next day). Consequently, there is no way Mrs. Darcy would have known about Bridget and Mark in time to get her a shirt too and offer it to her. Mark couldn't have brought it to Bridget, because she arrives alone at her mother's New Year's Day turkey curry buffet; Mark is already there, wearing the shirt his mother gave him, which suggests they split ways that morning, after their first night together.
Plot hole: In the scene where Michael Shannon attempts to rob John C. Reilly and Diego Luna, he takes the briefcase, looking for the check, but it is empty. Diego Luna then reveals he has the check in his pocket. In none of the previous scenes does Diego Luna have a chance to take possession of this check. The check remains in the briefcase, and the briefcase is always in John C. Reilly's possession.
Plot hole: How does Clifford, a ten-year-old boy, manage to steal a stereo, a surfboard and a dog from the airport without being caught?
Plot hole: Mrs. Tingle was tied to bed for longer time, fed by her students, but what about going to toilet within this period?
Plot hole: Near the end of the movie, Lance approaches Leon saying he's waited longer for this than anyone; however, he stated earlier in the film that the first encounter between Leon and his wife was in 1990, and another member of the V.S.A. said Leon and his wife were together in the Spring of '89, meaning he would have waited longer than anyone.
Plot hole: There is supposed to be no power when the Dragonfly ship reaches the island, but the lights are still on. At first, I thought it was just a lighting trick, but you can see the lights are on in the tunnels.
Plot hole: When Ward's son hits the switch marked "Do Not Touch This Switch", every light in the amusement park comes on, music starts playing, and the rides all start moving. It's a funny gag, but it seems unlikely that one switch would power every single thing in the amusement park, and that everything in the park has been left on "full speed." If that's the case, when Angelo first sent the two lookouts to the top of the ferris wheel, everything else in the park should have come on then too.
Plot hole: There is no way Dirk, Al, and Eva could have made it from the top of the fort to their camels, raced cross the desert and then hid themselves in the sand all before the train were to have met them. The train was barely visible when Dirk saw it through the scope which means it was much farther away to begin with.
Plot hole: The kidnappers initially ask for a ransom of $50 million. $20 million in $20s, $20 million in $50s, and $10 million in $10s. This translates to a grand total of 2.4 million bills (pieces of paper, that is) Every bill of American currency is 2.61 inches wide, 6.14 inches long, and .0043 inches thick. This makes roughly 2,791 bills to form a 1 foot tall stack. This means that the 2.4 million bills would take up a space of 96 cubic feet (assuming they are packed as tightly as possible). Also, since 490 bills make 1 pound, the 2.4 million bills would weigh (interestingly enough) just over 2.4 tons. No way they can move it.
Plot hole: When Delila finds out who Jimmy really is, she takes his tuxedo and is apprehended by the bad guys. She then turns on her homing device on her necklace. The office says it will take 20 minutes to get to her. From that statement to when the CSA finally arrives, Jimmy has time to go to Devlin's, write him a letter, discover water striders, find his suit, and get back to Delila and fight the bad guys. THEN CSA shows up. The timing is really off.
Plot hole: In the scene after Chris' disastrous lunch date with Caroline, he is seen signing autographs before getting into his limo; however, he starts making out the autograph to Amber before he has even asked her name. He tries to cover by then asking for her name, and acts surprised/shocked that it is indeed Amber. Both he and the fan start laughing before he spots Caroline and Rachel coming out of the hotel and pushes Jerry into the limo. (01:01:57)
Plot hole: When Daniel is in the air with the stolen plane from the Los Alamos air base Nat suddenly appears from behind. However, Nat had no chance to slip into the plane secretely as there was only one stepladder that had been in his mom's full view while she hugged Daniel good-bye. (01:25:30)
Plot hole: In one scene, he's driving from Los Angeles to Berkeley in a hurry, and crosses the bridge again (in the wrong direction). But the most direct route from L.A. to Berkeley doesn't require you to cross the Bay Bridge in EITHER direction.
Plot hole: When Pistachio and Jennifer go to the toy convention to find Bowman she says her name is Barbara, and Bowman invites her to his house. When Pistachio comes looking for her at the door (as the German Guy and the Snobby English Guy) he says he needs to talk to Jennifer Baker. Wouldn't he ask to see Barbara instead of Jennifer? Also Bowman knows her as Barbara and didn't say anything about him calling her Jennifer.
Plot hole: In the scene where bad cop says "security cameras picked up this" it shows the footage of Emmet "convulsing with the strange piece." If they had cameras down there, then they would've already found the piece of resistance. (00:08:10 - 00:10:10)
