Continuity mistake: When Coraline goes to see her father for the first time in his study, there are three boxes at the entrance. She enters, puts the Coraline doll down on the smallest box with the doll's legs and right arm hanging down, then she starts playing with the creaky door. When her father tells her to stop, the boxes have changed position and the doll's legs and arm are straight. (00:10:05)
Continuity mistake: When Coraline is in bed in the other world for the first time, she's holding the picture frame showing her friends face down. When the shot changes to her again, the frame is facing up. (00:21:35)
Continuity mistake: When Coraline and Wybie are flipped around Mr. Bobinsky's door on the way to the mouse circus, you can see that first they are on the outside of the door, then when they are in the house, it is the inside of the door. If they flipped on the door that way, they would stay on the same side of the door, not switch sides. You can tell by the curtain rod, you can see the ends of the rods where they are mounted only when they are in the house. (03:07:15)
Continuity mistake: During the other father's song, notice the red record player by the door and the position it's in, with the lid facing Coraline when he says, "making up a song". When the camera angle changes and he says, "she's a doll", the record player's position changes completely, with the lid now facing the wall.
Continuity mistake: During Coraline's first meal with her Other Mother and Father, just before Coraline says "I'm real thirsty." there are two drinking glasses to her right, the one she uses a couple seconds later and a smaller one. After the cut to the chandelier lowering, it goes back to Coraline and the smaller glass has completely vanished.
Continuity mistake: When Coraline first finds the door, we see her mother on her computer, with the "I Love Mulch" mug's handle facing the doorway so we can see the words. However, in the next shot of the mother, while the camera angle has changed, the mug has rotated itself and the words are still visible.
Continuity mistake: In the scene of Coraline's first dinner in the other world with the other parents, you notice the small water glass is full. Later, when Coraline says, "I'm real thirsty" there is a substantially smaller amount visible.
Continuity mistake: When Coraline firsts sees her Other room, the mobile is to the right of the fireplace. But later, when she gets back from the circus, it's to the left of the fireplace.
Continuity mistake: When the movers leave the Pink Palace we see Coraline's and her parents' luggage tied to the roof of the car. In a later scene afterwards, Coraline explores up the cliff and we see a view of the Pink Palace and the car and their luggage is removed. This was right before Coraline was startled off the falling rocks as the Cat was spying on her.
Continuity mistake: When Coraline goes to bed for the first time you see her looking over to the picture frame. You can see the picture of the two people and the board with the words "Coraline goodbye!" If you look closely the E is a 3 that's sort of hanging. When she picks it up and the camera has a shot of it as if we are looking at it from her view, the 3 turns into a E, then when she puts it back if you look closely again it turns back into a 3.
Continuity mistake: When Coraline is in the web thing near the end of the film, at first the web is colored black. It changes to a gray color when she climbs out of it.
Continuity mistake: The scene where Coraline is sleeping for the first time, the Coraline doll keeps changing from facing the camera to facing her in different shots.
Continuity mistake: At the dinner table early in the movie, Coraline says, "It looks more like slime to me." She then drops her fork into the chard and lowers her hand. But in the next shot, her hand is still up.
Continuity mistake: The Coraline puppet legs are very thin at the beginning of the film, yet once the scene where Coraline delivers the cheese to Bobinsky is shown, the puppet legs are at the normal thickness.
Answer: Opinion is divided - it's either Coraline's face, or the other mother. No-one seems able to decide which.
