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.
Alice in Wonderland (2010)
1 revealing mistake
Directed by: Tim Burton
Starring: Johnny Depp, Helena Bonham Carter, Anne Hathaway, Crispin Glover, Mia Wasikowska
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.
Alice Kingsley: This is impossible.
The Mad Hatter: Only if you believe it is.
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.
