Scenes filmed in Jordan required an AK-47 assault rifle with blanks but during rehearsals these would not enable the rifle to reload automatically. Consequently, real ammunition was used.
Reported to be the last feature film made with Fuji 35mm film stock.
Reported to be the first feature film ever filmed during live operations inside Gatwick Control Tower.
Certificated 15 by the British Board of Film Certification (BBFC) in October 2014.
