Other mistake: When the switch is thrown to electrocute Terrence and Phillip, it's pulled downwards. A few shots later, we see Cartman jump in to save T and P by turning the switch off. He also pulls the switch downwards instead of pushing it upwards. (01:06:05)
Continuity mistake: During the "La Resistance" number, during the verse, "They may stab you in the head, with a dagger or sword," We see a guy wearing blue with a blue hat on the left (probably Craig). In the next shot, he disappears, and in the next shot, he reappears. (00:50:05)
Factual error: During the press conference, the president says that at 5:00 AM the Baldwin residence was bombed. However, the Baldwins were sunning themselves. And, if the president was referring to Eastern time, it would have been 2:00 AM in Hollywood (sign in the background). (00:26:35 - 00:27:45)
Plot hole: The night of the La Resistance meeting, before Kenny appears as a ghost, Cartman can be seen putting a mirror and a rope into his backpack. These are items that The Mole requested they bring for the rescue operation, but they hadn't met The Mole yet. How did Cartman know what to bring? (00:41:25 - 00:59:15)
Continuity mistake: When Kenny dies, his heart explodes, leaving blood and guts all over the boys and the wall behind them. When the boy's mothers enter the room moments later, the boys, and the room, are spotless. (00:19:20)
Continuity mistake: When Winona Rider first appears on stage, Phillip's "P" is missing from his shirt as she passes them. (00:57:50)
Continuity mistake: Early in the film Satan is singing and has 4 fingers. When he asks Mr. Hat to join him in hell, he has 5. (01:11:20)
Continuity mistake: When the kids walk away from the movie theater, and they start to sing "Uncle F----," Stan moves to the back of the line, then in the next shot, he's in the front. (00:07:15)
Continuity mistake: When Mr. Mackey starts to spin Stan around at the end of the "It's Easy, Mmmkay" song, they spin anti-clockwise. Then, from Stan's point of view, they are spinning clockwise, (the background moves to the left). Then, from Mr. Mackey's point of view, they are spinning anti-clockwise again, (the background moves to the right). (00:16:50)
Continuity mistake: After Stan joins back up with the rest of the kids, he finds Eric and Kyle on the battlefield as they are climbing out of the trench. In the first shot of Stan before he speaks, Wendy is clearly standing in front of Gregory on his right and Butters is visible in the second row behind Stan. In the next shot from the side, the kids shift so that they are standing further behind Stan than in the previous shot, Gregory is now standing in front of Wendy on her right and Butters has completely disappeared. In the third shot, a girl in a pink shirt, who was not visible before, is now directly behind Stan and Butters has reappeared. (01:09:37)
Continuity mistake: Towards the end of the "Kyle's Mom" song - when his mother actually appears on screen - the position of her arms change between shots. In some shots, her arm are flat against herself, in others, she has her hands on her hips and her arms arched, etc. (00:30:55)
Continuity mistake: Before the 'It's Easy Mm-Kay' song, everyone is sitting in a circle. The boy on the right, by Cartman, is wearing a dark blue hooded coat, yet in a closeup, he has no coat but a light blue shirt on. (00:14:15)
Continuity mistake: When Mole digs out onto the stage, you can see Terrance and Phillip in their chairs, and the helmets they're wearing have a wire which is connected to the chair. Yet in a closeup of Mole talking to Terrance and Phillip, the wire goes straight up, and isn't connected to the chair. (01:01:05)
Continuity mistake: When Saddam is packing his suitcase for Earth, you can see a little doll in the case, on the right hand side of it. But in one shot when Saddam gasps because Satan says he's leaving him, the doll is on the left hand side of the case. Straight after that shot though, it's back on the right hand side of the case. (00:52:05)
Continuity mistake: When we first see the boys in the movies, Stan has a green drink in his left hand. Then in a closeup the drink isn't there, then in the following wide shot, it's back again. (00:04:45)
Continuity mistake: During the USO Show, Terrence is sitting in the left electric chair, and Phillip is sitting in the right electric chair. Just before they get electrocuted, they swap places, and then quickly swap back. (01:01:10)
Continuity mistake: When Terrance and Phillip are standing alone, and the big group of soldiers run towards them, the General is standing in front of them and Shelia is standing in front of the General. Yet when it cuts to a closeup of the General talking, Shelia has disappeared. (01:07:05)
Continuity mistake: When Kyle is searching for 'clitoris' on the computer, the mouse and mousemat next to the keyboard disappears and reappears continually. (00:37:55 - 00:39:00)
Continuity mistake: When we see the outside of Kyle's house, the doorknob is on the right of the door. When we see the inside of the house, the doorknob is still on the right. Do the Broflovskis have a magic door? (00:02:50)
Answer: Kyle placed Ike in the attic to protect him because Ike is Canadian, and if he was found, he would be placed in a concentration camp.
