When Jack is making a toast with Lloyd the Bartender, he says "here's to five miserable months on the wagon." At the beginning of the film, Wendy says Jack has been sober for five months. They had already been living at the hotel for a month in regard to the scene with Lloyd, so Jack should have said "here's to six miserable months on the wagon."
When Jack is using the ax to break through the door, he only breaks through one of the the recessed panels and says, "Here's Johnny". But when he hears the snowmobile and turns and the shot changes, two of the panels are gone without him using the ax on them.
When Jack is being interviewed for the job, there are numerous cuts between him and Ullman. If you look at the desk during the interview, you will see a pen that seems to dance across the desk, it keeps moving on the desk every time there is a cut between Jack and the man.
When Danny and Halloran are discussing "the Shining" over a bowl of ice cream, the shots of Danny change several times throughout the scene to show him having large dark circles under his eyes and ice cream on the sides of his mouth to barely visible circles under his eyes and no ice cream residue.
When Wendy visits Jack in the lobby while he is typing (where he gets very agitated that she has interrupted him, approx. 45 minutes into the film) he rips the current page from the typewriter and never reloads a new one; when she walks away and he resumes typing, (with no breaks in the dialogue/action) there is a new page already loaded.
When Wendy is explaining Danny's injury to the doctor, she says that at the time of the incident, Jack promised never to drink again and he's been sober for five months. Later, when Jack is describing the incident to the bartender, he says it happened "three goddamn years ago!"
When Hallorann and Danny are talking about "the Shining", the camera goes back and forth between close-ups of them. In one shot of Danny, his hair appears messy and wild, but the next time, we see him his hair is neat and his posture is more straight and attentive.
At the beginning of the movie, when Danny and Wendy are still in Boulder, we see Danny talking to Tony in the bathroom mirror. The Disney character Dopey Dwarf is on Danny's bedroom door; however, when the doctor comes to check on Danny after his incident, Dopey is missing.
When we see the elevators open, gushing blood, the elevator door opens from left to right. Earlier, when Wendy and Jack are being shown around the hotel, they are led out of an elevator thats doors open right to left.
When Stuart Ullman is interviewing Jack, he has a name plate on his desk. When Wendy finds the switchboard is out and has to use the ham radio, the name plate is gone. When Jack goes back into that room to remove the tubes from the radio, the name plate is back in the center of the desk.
While Wendy and Danny are in the bathroom hiding from Jack, the interior shots show snow accumulated in the corner of the window pane. There is no snow on the exterior shots of the window as Danny escapes. This keeps alternating between snow and no snow as the scene alternates from interior to exterior shots of the window.
When Wendy drags Jack into the food storage room we see a bunch of knives on a small wall. Wendy locks Jack in the storage room and Wendy grabs a knife. The knife she grabs was not there before and the other knives have moved around.
When Jack enters the hotel manager's office to disable the radio, there is a light switch on the wall to the right of the door. Earlier, when Jack enters the office to meet with Mr. Ullman for "the interview", there is clearly no light switch on the same wall.
When Jack leans over the model of the hedge maze in the hotel lobby, the size and configuration of the hedges differ dramatically from the design used in next overhead shot of Wendy and Danny actually moving through the maze.
Dick Hallorann opens the freezer door with his left hand and the door's handle is on the right. When the scene switches to inside the freezer, he is opening the door with his right hand and the door handle switches to the left.
As Jack is talking to Mr. Grady in the men's room, and Grady puts down the tray, it moves from between the second and third tap to between the third and fourth tap and back again several times during their conversation.
When Jack talks with Lloyd the bartender for the first time, you can see two errors: the pattern of the bar is lighted glass, wood and then lighted glass again. you can see that at the beginning, Jack sits and the wood part is right in the center of his body, one moment later it's near his left hand, and few moments later it's far away from his left hand.
When Jack is at his typewriter, and Wendy asks "get a lot written today?" there is a table and chair against the wall in the background. In the next shot of Jack, the table and chair have vanished, then reappear in the next shot.
(at around 1h 45 mins) Jack is chasing Wendy on the stairs. When the camera is on Jack, he has his hands up asking for the bat, then the camera goes on Wendy and we see Jack's hands down. The camera is back on Jack and his hands are up again.
When Jack calls Wendy after his interview, there is a woman behind him, in a chair, reading a magazine. Her body is turned completely to the right, with her head up. The scene cuts to Wendy saying, "Sounds like you got the job." When it cuts back to Jack, the woman is turned completely left with her head down.
As Wendy drags Jack to the storage room, she clearly unlatches the slide lock and pulls the pin from the lower lock. When she locks it back you can see that the slide bolt lock is latched shut, yet Jack still escapes. The push knob on the inside would only control the lower lock when the pin is out. Jack couldn't have escaped if door was locked on top.
The McDonnell Douglas DC-10 pictured in-flight as Dick Hallorann's trip from Miami to Denver's Stapleton Airport is Continental Airlines N658052 wearing Continental's Saul Bass designed "Jet Stream" livery with its "meatball" logo on the tail. The subsequent snowy scene showing a DC-10 landing is of a United Airlines aircraft wearing their 1974-1993 "Tulip" livery, also designed by Bass.
When Wendy gets up to run into Danny's room when he's screaming "Redrum", she has a cigarette in her hand. Though, when she gets through the door and into Danny's room to grab him, the cigarette is gone, without enough time for her to discard it.
When "Larry" is walking into Durkin's garage and the phone is ringing. Larry tosses his gloves on the desk next to a small box and answers the phone, and it is Dick Halloran on the other end. The scene cuts to Halloran talking on a pay phone at an airport, then back to Larry who turns to his right and the gloves are still visible on the desk next to Larry's left elbow. The scene then cuts back to Halloran at the airport for a brief moment then back to Larry and the gloves have mysteriously disappeared and the box has slightly moved.
Wendy's hand placement on the bat when Jack is chasing her up the stairs. Up until the time she hits Jack with the bat, her hands are half way up the bat but when she hits Jack with the bat, her hands are at the base of the bat.
When Jack is angry in the kitchen after his argument with Wendy, he knocks kitchen utensils off the worktops, a couple of steel tins hit and bounce back off the camera. You can clearly see Jack start to laugh, but he goes back into character as he walks down the hall.
The last picture of the arrival sequence in the beginning of the movie is an aerial shot. During this shot the helicopter rotor is clearly visible as the upper half of the view is shot through the rotor disk.
Just before Wendy and Danny enter the maze outside the hotel for the first time, they pass a hut near the entrance to the maze. Camera crew/equipment are noticeable in the reflection of the glass in the hut as they pass by.
[Around 02:08:19] When Hallorann arrives at The Overlook Hotel looking for the family, the overhead chandelier's pink lights are reflected off the camera lens on to the spot where his torso is in the shot.
The location in the film is supposed to be Colorado state in the United States. However, because the filming location was actually in England, all the television sets that can be seen in the movie have the distinctive European styling, especially the big black border around the picture tubes, and don't look like American television sets.
When Wendy brings Jack breakfast in bed, she brings him eggs made sunny side up. Any eggs should have been frozen processed egg product. Fresh eggs would not be available because all food would have to withstand 6 months of storage. Any milk would have to be powdered. Their provisions would most likely be the same as those staying the winter at the south pole station in Antarctica. Any perishable items like fresh produce or vegetables would have been removed prior to the departure of the staff.
A caption reads "THURSDAY" and then shortly afterwards we see Wendy and Danny watching The Road Runner Show with its distinctive theme song. In the late 1970s that show played only on Saturday mornings.
There are several large windows along a wall in the master bedroom of the caretaker's quarters. However, these windows cannot exist based on the architecture of the Overlook as seen from the external shot when Wendy pushes Danny out the bathroom window and down the snow drift. This is one of many intentional impossibilities in the architecture of the Overlook. Among others, there are doors where no room can exist, hallways that are impossible and stairways that could lead nowhere. This is to make the Overlook appear more labyrinthine and out-worldly.
The song played in the ballroom scenes is "Midnight, the Stars, and You", which wasn't recorded until 1932, 11 years after the scene takes place. This fits with the recurring theme of a time warp paradox.
When Jack Torrance is at his appointment with Mr. Ullman, he talks about the tragedy that took place during the winter of 1970. Here's a quote of the conversation: Mr. Ullman: "My predecessor in this job hired a man named Charles Grady as the winter caretaker. He came up with his wife and two little girls of about 8 and 10." Later in the movie, we see multiple shots of Charles Grady daughters "ghosts" talking to Danny. Some viewers are confused because the girls are dressed identically, and thus assume them to be identical twins, and think that the two-year age gap is a goof. But one girl is taller than the other and has a differently-shaped face, so they are not twins. However, it may be worth noting that while the characters are not supposed to be twins, they were in fact played by identical twin sisters, Louise and Lisa Burns, both born in 1968.
The first time we see Jack's typewriter at the Overlook Hotel, it is a small white typewriter. Later, when he is actually typing, it is a larger, blue typewriter. However it is entirely possible that Jack borrowed the blue typewriter from one of the offices.
After Wendy has locked Jack in the pantry, we hear him slamming against the door repeatedly in an attempt to escape. The door doesn't move an inch, yet, in the interior shot, we see the door giving when he's saying "go check it out" and slamming his hands against it.
When Mr. Ullman interviews Jack and explains why the hotel is closed for the winter, he finished his sentence while his left hand grabs his right. A second later, it is his right hand grabbing his left - a mirror image.
After Jack kills Hallorann, the head of the ax is bloody as would be expected. When Jack is subsequently chasing Danny through the maze, we see light reflecting off the ax, and the ax is very shiny where the blood previously was.
Someone can been seen filming the last scene toward the end of the film when Wendy runs out of the hotel and sees the man in the furry costume with the other man wearing a tux performing some kind of sex act. His reflection can be seen on the lamp to the left inside the room itself they're in.
Throughout the film, the Gold Room sign is located at the entrance of the Gold Ballroom. At the very end of the film, the sign is in the inside of the Ballroom as the camera exits while focusing on a picture of Jack. It doesn't make sense why the sign would be on the inside of the room if the sign is meant to be out in the hallway before you enter. (There is a theory that explains the moving sign with the clips/scenes are from different eras showing different Jacks.)
In his job interview, Ullman tells Jack the name of the previous caretaker which was, as Ullman says, Charles Grady. When Jack meets Grady later, he says his name is Delbert Grady. However, this is purposeful. The names are different to imply both Gradys have been to the hotel before, they are not the same character merely the same "entity" or soul being pulled back to the hotel, much like Jack Torrance's character.
In the film's final action scene, when Jack is chasing Danny through the maze, there's never any evidence of steam emanating from anyone's mouth from the cold; yet, it's so frigid, Jack actually freezes solid over night.
