When Alice climbs back up out of the rabbit hole, the estate where her party is being held is visible in the background. Many of the guests appear to be dancing, yet when Alice returns to the gazebo, all of the attendees are waiting for her exactly as she left them.
When Alice takes the Bandersnatch's eye away from the Dormouse and holds it in her giant-sized hand, the size of the eye increases from about the size of a marble to about the size of a baseball. When the Dormouse had the eye tied to her belt, the eye should have been about the size of a baseball (the size of the Bandersnatch's other eye).
When Alice eats the sweet bar labeled "Eat Me" to get herself enlarged and be able to pick the key from the table and starts growing. The camera first takes the shot from up and her thighs can be seen coming out of her skirt as she grows bigger. The shot continues from the front and it shows the dress getting shortened again from the knees and her thighs coming out.
When Alice is jumping over the heads to get to the Red Queen's castle, she sticks her foot in a puddle, clearly getting it wet and even shaking excess water off. However, in subsequent shots, her foot appears to be completely dry.
Right before Alice rides up to the White Queen on the Bandersnatch, the Queen has steps next to her horse, presumably to help her climb on. However, when they begin to march away to battle, the stairs simply disappear and the Queen is on the horse. Who moved the stairs?
While looking at the scroll, the Red Queen says she would recognize Alice anywhere by looking at her hair. Yet when Alice is in her castle under the name Um, why doesn't the Queen realize it's her? It is entirely within the
Queen's character to claim she would recognize Alice, and then later not actually do so. She also believes that all of her court members have overly large features when the rest of the characters know they are fakes. There are multiple evidences throughout the movie that the Queen is easily deceived.
The White Rabbit is shown in at least one scene with pads on his feet like a dog or cat. Real rabbits do not have pads on their feet, nor do they wear waistcoats, obsess about time, or get involved in politics. But as this is a fantasy rabbit, it is entirely feasible.
The dragon is referred to as both "Jabberwocky" and "Jabberwock" at different points of the movie. The shorter form is used to fit the rhythm and meter of a poem. Regardless of what it says in the book, the creature can be called whatever the film makers say it should be called.
Flipped shot. When Alice is riding Bayard towards the Red Queen's Castle, her Bandersnatch scratch is on her left arm, when it should be on her right. Also, the flower that the Mad Hatter had put on her dress was on the left instead of the right.
While Alice is riding Bayard, her wound from the Bandersnatch disappears momentarily.
When Bayard meets the White Queen, after he left Alice at the Red Queen's castle, she pets him, but the shadow of her hand doesn't meet the shadow of the dog.
When Alice is riding Bayard to the Red Queen's castle, the wide shots show the dog's back moving wildly up and down with Alice. In the closeups of Alice, she is hardly moving up and down at all.
In the first scene, Charles Kingsleigh proposes to extend his business to Rangoon and Jakarta. Batavia's name was changed to Djakarta in 1942, and Jakarta in 1972.
When the Hatter asks Alice if he's gone mad, she tells him he's "entirely bonkers." The word "bonkers" wasn't coined until after World War II.
While the red and white armies are marching to the "chessboard" battlefield, the sound of their marching isn't synced with their footfalls.
When Alice climbs aboard the Blood Hound, her ribbon arm band disappears during the ride. When she gets off the dog, her ribbon arm band is back.
Alice unlocks the tiny door when she first finds the key. The door magically closes but we don't hear it lock and we don't see Alice re-lock it. It is locked after Alice drinks from the bottle.
When The Mad Hatter is talking to Alice about when the Red Queen took over from the White Queen, you see the shadow of the camera circling around them you can also see the shadow of the camera man's legs while he is moving the camera around.
After riding Bayard to the Red Queen's castle, Alice has to jump onto floating stone faces to get over the moat. On her final jump, there are several faces left to get to the other end, yet after jumping she ends up on solid ground on the other end.
Whenever Alice changes size, the Dormouse remains the same height in proportion to Alice.
While riding the Bandersnatch to the White Queen's castle, Alice meets Bayard and asks him to guide her to Marmoreal even though the castle's name was never mentioned in the movie before.
If the Oraculum shows every date in the history of Underland, it should have shown the day the Jabberwocky attacked, allowing the denizens to prevent it.
When reciting the poem Jabberwocky, the Mad Hatter makes the common error of misreading the nonsense word "borogoves" from the original poem as "borogroves".
Hamish, while dancing with Alice, blames her "being distracted" on why she bumps into another couple. Except Hamish is leading, so if Alice bumps into someone else, it is because he made it happen.
Alice falls down the hole and lands on the ceiling. The next shot is her sitting up with her hair streaming upward/toward the ground. Yet her skirt seems to be glued to the ceiling as it lays perfectly around her.
Bayard is told to track a human female. No one gives Bayard anything to get a scent from. Bayard would find the scent when they get to the Hatter's table. Then Bayard leads the Red Knights, again, to where the Hatter and Alice are, but Alice is in Hatter's pocket (or hand, on his shoulder) so she is not leaving any scent behind.
The cake that makes you bigger is called "Upelkuchen". It is odd that it contains the German word for cake, "Kuchen", yet it is pronounced in a completely un-German way (kut-chen). This seems rather to miss the point of the name, as it makes no sense without subtitles.
