Deliberate mistake: In the chase through the tube station, Bond and Silva both slide down between the escalators. On the London Underground, this area has hard vertical signs at regular intervals, precisely to prevent people sliding down. (01:31:50)
Deliberate mistake: Manny refers to the pirate rabbit as the Easter Bunny, even though Easter never existed in prehistoric times. (00:33:55)
Suggested correction: And mammoths didn't hang out with sloths and smilodons either. It's creative license.
Deliberate mistake: When Connors becomes a humongous Lizard, his robe magically grows from a Medium size to an XXL. (01:06:50 - 01:17:45)
Deliberate mistake: In the finale, the main characters exit 'the fall' and climb up the outside of the vehicle. As the vehicle is travelling at thousands of miles an hour, they would have surely been sucked off instantly and most certainly would not have been able to maintain a grip on the ladder rungs as they climbed 'the fall'.
Deliberate mistake: When Julien is about to pull the switch to turn the power off in the Monte Carlo casino, the sign above the switch says "LE POWER." Monte Carlo is in Monaco, where the language is French, so the sign should be in French. Obviously "THE" is in French as "LE." But "POWER" is not in French. The sign should have said "LE POUVOIR."

Deliberate mistake: When Bilbo finds The Ring, he kneels down to get it. In the prologue in Fellowship Of The Ring, Bilbo is lying on the ground. The direction he looks toward when he overhears Gollum is also different.
