Plot hole: Prior to the final show, when the horsemen are performing separately at different locations in London. [Scene X] Jack is busy with his card swap trick. While others are doing their tricks too, [Scene Y] McKinney is believed to be tricked once again by his face sharing brother at another location... Dylan gets a call and then he calls everyone to wrap up and meet somewhere. [Scene Z] Jack also wraps up and leaves the place... OK. Later after the expose in final show McKinney tells the story about how Jack successfully hypnotized his brother [in the Scene Y]. How could Jack be at two different locations at the same time? He was performing somewhere else when he did hypnotism at another location and then wraps up his trick back where he started.
Plot hole: When Moana first meets Muai, she opens her necklace to tell him he will restore the heart. Muai sees the heart but doesn't get scared until he sees it again on the boat. He should have been scared the first time.
Plot hole: There's no way that Eddie and Nana left the flooded theater without getting a single drop of water on them. The water flooded up to the ceiling and there's no other way to exit besides the front doors, and Moon's secret exit, which also floods. They do not leave through either way.
Plot hole: When Norm is stuck under the satellite tower after disposing of the condos, he has flashbacks to numerous moments earlier on in the movie. One of the flashbacks is of Socrates saluting Norm, but the moment where Socrates salutes Norm did not occur until he was on the cargo ship being shipped off to New York and was something that he did not see Socrates do; there would be no way for Norm to have this flashback. (01:18:00)
Plot hole: When Eddie Mannix first views scenes from the movie Hail Ceasar there is a scene depicting Saul of Tarsus (St Paul), but the movie-in-movie's climatic scene and speech are set at the crucifixion of Jesus which happened several years before the events depicted as happening to Saul / Paul.
Plot hole: When Bridget phones Mr. Darcy, she is told that he has left and is in a taxi on his way home, so Bridget decides to walk to his house where she sees him get out of the taxi and meet his ex-wife at the door, and Bridget thinks they are back together. The problem with this is that she is heavily pregnant and she walks a fair bit across London - hard enough to do at the best of times - and that Mr. Darcy was already in the taxi going home, but she managed to arrive at the same time at his house.
Suggested correction: Mr. Darcy may not have gone straight home. He made have needed the taxi to take him to do an errand, he just doesn't mention this when leaving. Plus, there could have been heavier traffic that we don't see which he could have been stuck in.
Ever gone through traffic in London? During the day it's a nightmare. But in BJ Diary, Mark's mum tells Mark Bridget lives not so far from him, if I'm not mistaken.
Plot hole: Rafe is not a supernatural being, and besides not suffering any fatigue at all missing his sleep to do his pranks, some are outright impossible to execute and perform overnight for a person of his age (most likely for an adult in their prime too). Covering the entire hall and corridors, plus the principal's office, with post-it stickers requires a ridiculous amount of stickers to begin with, and arranging them creatively covering the whole walls, floor to ceiling, so that they create drawings, is an insane concept. Even more insane when it's the opening prank, anything he does later in the movie including the big movie finale requires less labor and time than his first act did.
