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: When the police search the white car and the barn they fail to find the compartment in the car behind the boot in which the decoding equipment was hidden. This is completely improbable. It was a standard car, the compartment was not a secret add on, and the police were supposed to undertake a thorough search of everything.
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 Lalaina is in her depressed "Bell Jar" phase, she's complaining to the psychic hotline counselor that she's freaked out by the idea of having kids because she "can't even take care of a Chia Pet". But earlier in her documentary, she'd talked about how starting at age 13 she had to become the responsible one, buying food, taking care of and parenting her siblings. Which contradicts the portrayal of her as someone who can't take care of anything.
Plot hole: When Finnegan is in the water and the explosive charges go off, Finnegan should be dead from concussion, and the explosives are big enough to have caused his death by them flinging him quite high out of the water. What happened to Finnegan was pure fantasy.
Plot hole: Lois and a friend of hers are watching Non and Superman fight. But this is totally senseless, because Superman had been flying around Metropolis and chances are slim that he appears in the very same spot to let Lois watch him. And, second and most important, should any doubts arise, the panning angles of the camera never show Lois's building, with the big broken window and the flag poles.
Plot hole: It is highly unlikely that the murderer knew Phil was going to put his ear to the stall when he heard the babbling. It is even more unlikely that the murderer is going to get him on the first stab through the stall. (Which also requires a lot of strength). We also have to assume that he spent time hanging out in the bathroom knowing Phil would go there to begin with, and that other two men with weak bladders were doing the same simultaneously forcing the victim to go to the stall to begin with. (00:07:45)
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: 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.
