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.
Alice in Wonderland (2010)
1 deliberate mistake
Directed by: Tim Burton
Starring: Johnny Depp, Helena Bonham Carter, Anne Hathaway, Crispin Glover, Mia Wasikowska

Continuity mistake: Alice's necklace keeps disappearing and reappearing after falling down the rabbit hole.
The Mad Hatter: There is a place. Like no place on Earth. A land full of wonder, mystery, and danger! Some say to survive it: You need to be as mad as a hatter. Which luckily I am.
Trivia: Alice's impending battle on the "frabjous day" with a creature referred to as a "Jabberwocky" is a central plot point, and refers to Lewis Carroll's famous poem "Jabberwocky," from which other characters in the film, such as the Jubjub bird and Bandersnatch, are derived. However, the titular creature of the poem "Jabberwocky" was NOT a Jabberwocky, but a Jabberwock. For whatever reason, the writers of the film chose to call it by the [admittedly similar] title of the poem instead of the actual name of the creature. (For the full text of the poem, see http://www.jabberwocky.com/carroll/jabber/jabberwocky.html).





Answer: It could be time moves differently in Wonderland, than in the real world. In many time machine movies, the Hero goes off on his adventures, then returns as if no time has passed.
