Corrected entry: Carl could have easily broken through the windows and escaped from Sam's ghost without throwing the hook at Sam, which instead causes fallen glass in the window to impale him and kill him.
Corrected entry: The storyline seems to change throughout the movie. First off, the plot was originally that Willy was only supposed to mug Sam and get his wallet, but not actually kill him. Carl confirmed this to Willy at Willy's place. But then later the storyline completely changes that Sam claims he was deliberately murdered for finding out Carl was laundering money at the bank (Ode Mae threw in that last part). Two different motives that conflict one another.
Corrected entry: When Oda Mae takes four million dollars from the account, she hands him one tiny piece of ID. But the name on her ID wouldn't match the name on the account.
Corrected entry: When Willie Lopez is mowed down in the street, his body is shown landing on the pavement near the wheels of a vehicle. When the camera comes back to part where Willie's soul leaves the body, his dead body is now on the hood of the vehicle and not in the street.
Corrected entry: After Oda Mae was talking to Molly in her home for the first time, Oda Mae leaves the room annoyed. When she says "Have a nice life, and you, have a nice death", she points to the wrong characters.
Corrected entry: When Sam is terrorizing Willy in Oda Mae's bathroom, Sam turns on the sink faucet and the mirror above the sink is clear. In the very next shot, steam has instantly appeared on the mirror for Sam to write "Boo" on.
Corrected entry: When Sam is on the train and sees the other ghost, the 'train ghost' gets up and looks at Sam, then starts yelling at him. How does the train ghost know that Sam is a another ghost? Sam certainly can't tell between ghosts and humans.
Corrected entry: You are you not allowed to smoke on a NYC subway nor is any advertising for cigarettes permitted. So there would not have been a cigarette vending machine for the train ghost to smash.
Corrected entry: During the second time Oda May and Sam are talking, Oda May keeps looking right at Sam even though she insists that she can't see where he is.
Corrected entry: The whole time Sam is a ghost, he is trying to touch things but can't supposedly, until the ghost in the subway shows him how. But during that whole time that he couldn't touch things, Sam could still go on the subway, (he would be able to jump through the subway doors, but would not fall through the floor when he landed) sit on couches, (he would sit on the couch, the cushions would move, but I'm sure if he tried to move the couch he wouldn't be able to) go up stairs, etc. It was a major part of the movie that he could not touch things, yet, he was touching things the whole time.
Corrected entry: When Oda Mae and Sam are meeting Lyle Ferguson, in every shot of Lyle you can see a blonde woman and man in a black suit at the desk behind him. When Oda Mae sits down at that side both people are gone. There wasn't enough time for them both to get up and leave. (01:26:25)
Corrected entry: In the scene where the penny is pushed up the side of the door, the head is facing upwards. In the next shot, the head's position has moved 90 degrees to the right.
Corrected entry: When Sam returns to Oda Mae's, a few other ghosts are seen entering. When they enter, it makes the sound effect for a ghost passing through a solid object. However, the door is wide open so they aren't passing through it. (01:18:05)
Corrected entry: When Sam plans to withdraw the money from Rita Miller's account to foil Carl's plot to launder money, Sam tells Oda Mae he needs her to get some of her fake IDs. The only way he would know that Oda Mae once made fake IDs is if he was with Molly at the police station when Oda Mae's police record was pulled and the officer told Molly that Oda Mae was arrested for making fake IDs. Sam was not with Molly, as he was already dead.
Corrected entry: When Oda Mae is closing the account and getting out her ID she dumps out the contents of her purse. In the next shot and all of the following shots, the plethora of items on the desk is replaced with a white paper. (01:28:35)
Corrected entry: When Sam gets killed and gives chase to the killer, he steps into a puddle and makes it splash.
Corrected entry: Willy gets inside Molly's apartment very quickly after Carl gets her to go out and take a walk with him. He's unable to get what he came for, and then goes straight to his house, where he contacts somebody on the phone - it can only be Carl. His explanation for why he couldn't get it? "She came home." But since it can only be Carl he was talking to (this is made clear by Carl's visiting Willy later on) Carl knew perfectly well that Molly came home. It's Carl that Molly was with - he'd have known full well that she left his company.
Corrected entry: At the end, after Sam moves the penny to convince Molly that Oda Mae is telling the truth, they all go into the apartment. Now, knowing that a murderer, Carl, is on his way to come and get them, you would think they would all get out of there as soon as possible. Instead, they wait around until Carl shows up, and then act all surprised and run when he gets there.
