Continuity mistake: When the Devil is talking with Marino you see the Devil holding his hand up. When it cuts he is holding his hand on the arm rest. (00:09:30)
Continuity mistake: When Adrian and Cassius are talking about ruling the earth you see Cassius looking up. When it cuts he is looking at Adrian. (00:10:00)
Audio problem: When the demon pulls the devil's pinky off a demon says "gross" but his mouth never moves. (00:12:45)
Revealing mistake: When the priest is running and jumping down the stairs to the subway, he bounces up again, as if he fell on a mat. (00:15:25)
Continuity mistake: When Nicky talks to his roommate for the first time and makes the "deep South" joke, you see Nicky start laughing. At the same time he tips his head down, but when it cuts from behind he is looking straight forward. (00:18:40)
Visible crew/equipment: In the church scene, when the priest stops dancing on the pizza and the camera goes up you can see in the left middle of the screen a camera just poking out as when the priest talks it goes right to him. (00:20:20)
Continuity mistake: When Nicky falls asleep outside we get a view from him from above. We can see the bottle lie right next to him. When it cuts the bottle has moved away from him. (00:23:55)
Continuity mistake: Durring the second encounter with the blind man, after Nicky and Valerie bought their ice cream, watch as the blind man runs into the light pole and in the backround Nicky and Valerie are turning the corner. In the next shot Valerie and Nickie are turning the corner that they have supposedly already turned. (00:28:10)
Continuity mistake: When Nicky and Valerie get ice cream, Valerie orders a vanilla cone, while Nicky gets chocolate. However, when we see them later, around the time when they meet up with Adrian, you can see Nicky's cone at the bottom of the screen and he has vanilla instead of chocolate. (00:29:15)
Continuity mistake: All throughout the scene where Nicky changes the Coke the latch on Beefy's collar keeps moving around. (00:32:55)
Continuity mistake: In the movie someone says "listen to this" as he holds up a Chicago album. The song playing is "Does Anybody Really Know What Time It is?" That song is from the Chicago Transit Authority album. The album the actor holds up is Chicago V. (00:40:10)
Continuity mistake: When Nicky is floating in front of Valerie's apartment, you can see that she 's holding a small teddy bear. Whenever the scene cuts back to Valerie, the teddy bear changes position everytime. (00:46:00)
Continuity mistake: When all the people in the wheelchairs crash with the bus they fall on each other. When it cuts, they all have changed position. (00:49:20)
Continuity mistake: When the devil is falling apart and his 2nd ear falls off, he tells Nicky he cannot hear him, and asks the demon by his side who catches it to put it back on his head. But towards the end, when the devil is reduced to no more than a mouth and 2 arms, he is able to have a conversation with his demons about what's going on and hear them perfectly. (00:52:05 - 00:58:50)
Suggested correction: Its not clear that they are actually having a conversation, he is just a mouth and two arms that can only talk and hold itself up. They respond to him because he can hear but he doesn't even respond to them. Its not illogical that Satan was talking to himself while deaf and falling to bits.
Revealing mistake: When Nicky shoots goodness at a group of demons, one of them bites off a part of one of the rabbits. In the last shot of that demon, it is extremely obvious that the bunny that he is holding is a stuffed animal. (01:08:00)
Suggested correction: Gonna be honest - I genuinely think the fact the rabbit is replaced by a ludicrously OBVIOUS stuffed animal is kind of an intentional joke in itself. The rest of the effects in the film are very solid for the time, whereas it's laughably blatant that the rabbit is a stuffed toy. The fact that the movie lingers on several shots of it with its button-eyes, unrealistic "cartoon" dimensions, etc. kinda tells me you weren't meant to take it seriously. At best, it could maybe be reclassified as a "deliberate" mistake, but even then, I don't think I'd classify it as such.
Continuity mistake: In the scene where Beefy and Todd are sitting on the couch, watching the globetrotters' game, Todd says something like "this is not good", then Mr. Beefy says "where the heck is Nicky", but Beefy doesn't move his body or lips at all. (01:15:45)
Revealing mistake: When Nicky is hit in the head by an officer, the baton obviously bends off his head like rubber.
Continuity mistake: When Nicky is playing basketball with his brother, they both move around between the shots, first Nicky is over the half court line, then back, then his brother is inside the three point line, then more towards the middle. It happens several times with both of them.
Continuity mistake: When the devil starts deteriorating, the first thing to fall off of him is his pinky finger. Later, when the devil is deteriorated down to two arms and a mouth, he has two thumbs and eight fingers.
Other mistake: When Nicky is expressing his trepidation about going up to the Earth realm, he states that he's never even slept over at a friend's house. Later when he is on Earth, Beefy has to remind him to try sleeping, as Nicky had no idea what it was.
