The chase scene at PNC Park was filmed on August 22, 2010, during an actual game. The Pirates beat the Mets 2-1. John Singleton wanted to film a chase scene there, which was not in the script, with a small crew with Taylor Lautner doing his own stunts.
This was the final film that John Singleton directed before his death on April 29, 2019 at the age of 51.
Shawn Christensen said that the story for the film was taken from a single idea of a teenager who sees a photo of himself on a missing persons website. He completed the first draft in two months.
John Singleton: Can be seen on board the train wearing a tan shirt sitting in a booth when Karen goes to get food for her and Nathan. He is also seen again when Nathan enters the same room.
