When Casey goes undercover, she has the name Mia. Katherine McNamara, who plays Casey, played a character named Mia on Arrow (2012).
Most of the opening scenes were shot in and around University of Ottawa, Ontario, Canada.
Twice, when Casey gets a call to visit her brother in prison (one which is never named in the movie), viewers see an aerial shot of Philadelphia's uniquely-constructed (and therefore easily identified) Holmesburg Prison which was decommissioned in 1995.
Tonjha Richardson's character, Judge McNulty, shares a surname with the movie's co-writer, Megan McNulty.
