When Christopher Meloni was interviewed about this movie, his response was, "I gave a good three minutes..."
The film was originally to be directed by William Friedkin and star Nicolas Cage. Production problems forced Cage and Friedkin to leave. In late February 2015, John Travolta was in talks for the lead.
The nightclub action sequence was filmed at Axis Nightclub, a popular gay nightclub in Columbus, Ohio.
The film's tag line -- "I lay my vengeance upon them" -- is a direct reference to a line frequently spoken by Samuel L. Jackson in Quentin Tarantino's 1994 film "Pulp Fiction," in which Travolta co-starred.
