Safe (2012)

This is a solid movie. After losing a rigged fight, the Russian mafia murders Luke Wright's (Jason Statham) wife and bans him from future competitions. He wanders the streets of New York and notices a frightened 12-year-old Chinese girl at a subway station being pursued by the same thugs. Mei (Catherine Chan) is an orphaned math prodigy forced to work for the Triad. She is told to memorize a long code that can be used to open a safe. Luke decides to defend her and determine what is being kept in the safe.

A class from a Catholic School in downtown Philadelphia was used for a scene depicting a class in China.
