Other mistake: When Jack Nicholson is talking to the manager of the Overlook Hotel, the manager mentions the death of two girls aged 8 and 10. When Danny sees visions of the two girls they are unmistakably twins, not different ages. A quick look at the IMDb (http://uk.imdb.com/title/tt0081505/fullcredits) proves they are - Lisa and Louise Burns, both born in 1968.
Other mistake: After Ethan crashes the Impala, he shoots at Keifer to make sure he's dead. Keifer's head and torso are on the hood of the car, but the shots break the back window on the driver's side. (01:13:05)
Other mistake: There's no way for Shelly to fit his masks, a speargun and other items in the small box.
Suggested correction: No, but we don't know exactly what he might have brought. The first time we see him they're picking up Vera, so it's most likely he brought another bag that could contain the items. He only said to Vera that the small bag was his whole world, but he just met her (Andy mentioned he got him a date for the trip) and he's trying to get her to warm up to him.
Other mistake: In the scene when Robert gets caught up in the trap by Grand Central Terminal, there are no traffic lights on the upper street that they show him being suspended from.
Other mistake: The clocks as we learn later in the film stop at 03:07 due to that being the time the witch died. However, the grandfather clock we see for the first time has stopped at 03:07. We then see it stop at 03:07 the next night too. However the minute hand is in a different spot to when it first stopped - it should have stopped at precisely the same point. (00:13:05 - 00:18:50)
Other mistake: When Jaws breaks the glass in the control room, it shatters and flies everywhere, but the water doesn't even move or give any indication of flooding the compartment.
Other mistake: In the scene where Dr. Isaacs is in the teleconference with the Umbrella Board of Directors, there are several glasses of water sitting in front of each individual hologram. At the end of the teleconference, the holograms of the board members disappear, but none of the glasses follow suit. This tells us that the glasses of water were physically in the room with Dr. Isaacs, for absolutely no reason, given all the other attendees weren't really there. (00:17:40)
Other mistake: In the shower scene, Marion Crane's palm looks water wrinkled as if she's been in the shower for quite a long time even though she was only in for a few moments before Norman stabs her. Also, when Norman drags her out of the bathroom, Marion's legs are stiff and together and she has her toes pointed.
Other mistake: Both times that Father Merrin ventures into the sacrificial chamber beneath the church, as he is walking down the flight of stairs, the rock wall behind him is well lit as if there were another lamp sitting right in front of it. In the shot immediately after it, the rocks are in total darkness, even though he has not moved much. He is already far from them in the first place, so the light could not have reached the rock wall and illuminated it so brightly.
Other mistake: The killer leaves the corpses of the Dean and Parker where they are and walks away, but they later appear in the room at Stanley Hall.
Suggested correction: That is because the killer is moving around the bodies. Just like when Damon is killed. His body is not where it was left when Alicia Witt comes back with the cops.
Other mistake: When Evie is in the library and all the book cases start to tumble over, if you look at one of the corner book cases you can see a piece of paper landing on it and the books are clearly painted on a flat piece of cardboard. (00:13:30)
Other mistake: As Lionel is hanging from the ceiling and the zombie priest and nurse come toward each other, the pitchfork that Uncle Lez shoved into the priest impales the nurse and it is covered with blood. A split second later it is clean. (01:22:45)
Other mistake: We know that the blob dissolves flesh and hair and that it can also burn wood (since fluid coming from the blob burns a small spot on the desk in the hospital) and that it can dissolve bullets, but despite this obvious acidic state, the blob doesn't dissolve plants, walls, glass, concrete, metal, nor sticks and twigs.
Suggested correction: It can control its functions otherwise it wouldn't be able to exist.
Other mistake: When they are all on the beach and Simon kicks the zombie, which flips over and spits in his face. It hits his whole face, and some of his chest, yet later in the movie he has just one cheek effected by the "acid".
Other mistake: After Van Helsing realises Dracula's coffin is in the cellar of Michael Gough's house, he hears a scream and runs to find the housekeeper Gerda overwrought and hysterical. He needs to find out where Dracula has just gone, and so he gives her a slap. It's hilarious how loud the sound of this is.
Other mistake: In the last shot of the film, the zombies are walking across the bridge to New York City. Below, there are cars on both sides of the bridge driving to and from the island with absolutely no concern for the chaos that is supposedly taking place. I guess the filmmakers couldn't stop traffic for a few minutes to get the shot?
Other mistake: Everytime it shows a window it is morning, even if the scene is supposed to be at night.
Other mistake: Near the end, as Van Helsing parts the wooden fence and enters St Botulph's churchyard, the camera tilts up and catches two builders on top of a construction sight watching the filming.
Other mistake: When the main guy and the blond-haired woman investigate the house of the guy who got hanged in the very first scene, October goes outside to smoke. She is seen in a construction site. Later, when they go to find October, we discover that the site is way down the street. I don't know why she decided to stray so far from the house to the site.
Other mistake: When Ben lies wounded in the open, we are treated to a solar eclipse followed by a full moon. These events must be 2 weeks apart. Long enough for Ben to have grown a beard (which doesn't happen), but too long for him to survive without water.
