Continuity mistake: Where Swazye and Moore are at the pottery wheel, seconds after their hands and arms had been smeared with clay, they're clean.
Suggested correction: The director explained this in the commentary. The scene where they are clean isn't meant to be immediately after the clay pot scene. It was just the same evening.
Continuity mistake: When Carl gets killed by the falling pane of glass, his hand moves downward and removes some of the blood. In the next shot, more of the blood is missing.
Continuity mistake: In the subway scene with the ghost that tells Sam how to move stuff, the crazy ghost hits the cigarette machine and about 5 or 6 packs fall out. In the next scene, there are loads of them in a pile on the floor and we haven't seen any more come out.
Continuity mistake: After they take $4 million from bank they walk outside where a young woman with long black hair, blue blouse, gray dress, black purse and white shoes walks by Oda Mae. Sam and Oda Mae argue for a few minutes, over what to do with the check. When they walk over to the nuns, the same woman walks by Oda Mae again.
Continuity mistake: Toward the end of the movie, Sam is weakening and is seen falling down. When he gets up he staggers over to the window before falling down again. However, he falls in the exact same place he did before - several feet from the window.
Continuity mistake: When Oda Mae is pretending to contact Mrs Santiago's dead husband she first pretends it's too difficult and one of her sisters moves to hand her back her money. When the bill is extended to Mrs Santiago, it's folded the long way and held by the sister at the very end. When Oda Mae pretends to feel something and the shot changes, the bill appears to be folded the other way and the sister is holding it in the middle. (00:40:25)
Continuity mistake: When Carl is pulling Molly off the ladder and putting a gun to her head, you clearly see him thumb back the hammer of the pistol three different times. A semi-auto only needs to be cocked once, and then only if it's a single-action.
Continuity mistake: When Carl is sitting alone at his computer in his office, having found his fake bank account emptied, a glass of water can clearly be seen next to Carl's computer. However, after he sees the empty chair (that Sam is sitting in) roll past him, the next shot of Carl's computer shows the glass of water now gone.
Continuity mistake: When Carl and Willy are storming Oda Mae's apartment the lock on the door magically changes. In the second shot of the lock, it has a hole through the metal part. However, when he shot the door open, it didn't put a hole in the metal. (01:40:25)
Continuity mistake: When Oda Mae and Sam first go to Molly's apartment, Oda Mae is seen walking across the street wearing black shoes. They appear to be flats or sandals or something like that. After Oda Mae rings the bell and speaks to Molly unsuccessfully, she turns and walks down the building steps to leave and she is now wearing white sneakers.
Continuity mistake: When Swayze is walking in the street, he passes the same woman in a checkered suit twice, without either of them having changed directions.
Continuity mistake: Right at the end, when Molly can see Sam as a ghost before he goes to heaven, they kiss. After the kiss, Molly and Sam open their eyes at the same time but in the next shot, Molly just started opening her eyes.
Continuity mistake: When Oda Mae is with Lyle Ferguson, he asks her to sign a paper that closes an account. Then he gives her a another paper to sign that is yellow. When she hands it back to Lyle, it is white.
Continuity mistake: When Willie breaks in and he is attacked by the cat, the position of the keys left by Molly changes between shots.
Continuity mistake: After they give the nuns the money, when Oda Mae spits at Sam, a woman with short dark hair in a green blouse, green blazer and long green skirt is walking towards Sam, past Oda Mae. Sam then says "I love you Oda Mae," and the same woman is now walking past Sam towards her.
Continuity mistake: Throughout the whole movie, Mollys bangs are short. In the end when shes talking to Sam they are longer, below her eyebrows.
Continuity mistake: When Oda Mae goes over to Lyle's desk and sits down, we can see his nameplate on his desk which reads Lyle Ferguson. In the ending credits it's spelled Fergeson.
Continuity mistake: In the film, Willy shoots the lock off Goldberg's door with a Walther PP but when he is looking around the flat he has a Walther PPK.
Continuity mistake: Towards the end when Carl has his gun in Oda Mae's face, he cocks it twice.
Continuity mistake: When Carl throws Molly off his back towards the end of the movie, he throws her into trashcans. They fall over twice.
