Other mistake: When Alice's ship is being chased, she orders her crew heel to port (turn left). Instead, it turns heel to starboard (right).
Continuity mistake: When time freezes, we see the Hatter's family freeze in the ant farm. When time is mended, he holds the farm close, and his family should have unfrozen at the top of the sand, but they aren't there.
Suggested correction: You might have to look closely, but they are there.
