Factual error: It's a superhero movie, but the human Catwoman escapes Batman by jumping off the building, onto a train moving at full speed, in a fall that is shown taking at least 10 floors (first shot, she is still upside down) + another 10 (when she flips so she can land on her feet). Over twenty floors of casual, unassisted freefall jump feel a little over the top already, and again, it's on the top of a moving train, that alone should be impossible to happen the way it does here, not affected by the lateral speed of the train at all.

Directed by: Justin Copeland
Starring: Jennifer Morrison, Jason O'Mara, Stuart Allan, Sachie Alessio
Continuity mistake: Bruce and Selina sneak away from the party while Bruce's neglected childhood friend fetches the drink. The bottles on the shelves behind the counter change between shots when he goes "Seriously? Both of them?" It's like a portion of the leftmost shelf has been sliced off for the close-up. (00:05:00)
The Riddler: Riddle me this - "The less of me you have, the more I am worth " what am I? Answer - A Friend.
Trivia: Peyton List voices Poison Ivy. In the TV show "Gotham", List plays Ivy Peppers, who becomes Poison Ivy.
