Continuity mistake: When Alice leaves to think over Hamish's proposal and chases after the White Rabbit, the heels on her shoes change, but when she falls into the hole the heels are back once again.
Continuity mistake: Alice's necklace keeps disappearing and reappearing after falling down the rabbit hole.
Deliberate mistake: When Alice jumps on the dog and they start running, her dress and her hand-band suddenly changed side. Probably they mirrored the image, and instead of going left as directed, it felt more accurate to go right.
Continuity mistake: In the Red Queen's courtyard after small Alice trip with Bayard, the Rabbit gives Alice an upelkuchen cake to grow. When she starts growing you can see she has a smudge of cake above her lips, but after the change in shot, it is gone.
Continuity mistake: During the execution scene, the executioner moves the ribbons of the hat "to see better" but when the angle changes the ribbons are where they were before.
Continuity mistake: In the beginning of the film when Alice is laying in bed her father shows her how to wake up from a dream by pinching herself. He demonstrates by pinching her upper arm on the bicep. Switch camera angle and he is pinching her on the shoulder, when the camera switches back he is once again pinching her arm.
Continuity mistake: When Alice first sees the tiny door (having just dropped into the rabbit hole) the keyhole is on the left-hand side of the door, but when she later uses the key to open the door she puts it in the right-hand side.
Continuity mistake: When the red queen is sitting in her chair and she is talking with Ilosovic Stayn, her lipstick is heart shaped. But when the camera switches to the side, her lips are fully covered in red and when it switches back it is heart shaped again.
Revealing mistake: In a close-up, just after the defeat of the Jabberwocky, the White Queen collects the Jabberwocky's blood dripping from its teeth into a vial. Cut to a wider shot with the vial just over half full, you can see that the drips are still being caught by the vial (ie, they don't drop past it onto the ground), but the level of blood in the vial doesn't rise, revealing that it is done in post-production.
Continuity mistake: When Alice comes back out through the rabbit hole her left sleeve is ripped at the seam. Then when she's in the study talking about her business plan, the sleeve is intact and connected to her dress.
Visible crew/equipment: After Alice rejects Hamish's proposal she does a bit of the Futterwacken, and when it cuts to a shot of everyone in front of the gazebo, the blue tape mark can be seen on the grass in front of Lord Ascot. It looks like there's also a yellow tape mark on the grass in front of Faith Chattaway. (01:38:15)
Continuity mistake: During the shrinking/growing scene the key and flask on the table keep changing positions between shots.
Continuity mistake: When the movie starts and Alice is laying in bed, her head keeps swapping from resting totally on the pillow or just the half of it.
Continuity mistake: When Alice falls through the "ceiling" in the round room there is a hole created by her coming through. The room rotates 180° so the ceiling becomes the floor. Through some miraculous occurrence the hole in the floor is no longer there. (00:13:27 - 00:13:55)
Continuity mistake: When Alice sees the box with the "Eat me" pie, the lighting and position of the box changes between shots.
Continuity mistake: When Hamish proposes to Alice the scene goes back and forth from them to the audience. In the first shot of the audience there is a bearded man behind Imogen's left shoulder. In the next shot he is standing some steps to the left behind a post. The next shot he is back behind Imogen's left shoulder. In Imogen's closeup he is now standing behind her right shoulder and when Alice runs off he is back behind her left shoulder. (00:10:38 - 00:12:02)
