Goofs

About 40 minutes into the film, in the location shot of the Chinese gang preparing to steal the dinosaur skeleton, you can clearly see St. Paul's Cathedral in the distance with two 1960s tower blocks (presumably the Barbican) on either side.

When the nannies are searching the dinosaur skeleton, Hettie observes that if it fell on them, they would be the first people to be killed by a dinosaur in 2 million years. Dinosaurs actually became extinct about 65 million years ago and humans first emerged only about 500,000 years ago, so Hettie is wrong on multiple counts.
