This movie was conceived as a "thank you" project by producers Ian David Diaz and Julian Boote to the cast and crew of their first feature The Killing Zone (1999). The idea was to use revenue from their first movie to finance a small film anthology written and directed by cast and crew members. The choice of genre was open, and the only stipulation (aside from budgetary constraints) was that each story must be set in one bed-sitting room of a tenement building. As it turned out, all the writer/directors, independently and without discussion with each other, chose a thriller/horror genre, thereby setting the overall tone of the movie.
Budget constraints meant the black harness actor Giles Ward's Assassin character wears at the climax of the first story, "Need to Know", is also worn by Melissa Simonetti's character Bernadette Pettiford (it holds the explosives strapped to her), and camera operator Cliff Harden (playing a body guard) in the last story, "Shrine". Weapons the Assassin uses in "Need to Know" are also seen and/or used elsewhere in the film.
The Assassin gives his guns names after ex-girlfriends. They are: Marietta (or Super-Marietta) for his Python 357, and Petula for his submachine gun. The exception is his pump-action shotgun, called Thor.
A scene cut from the first story, "Need to Know", showed the Assassin obtaining information regarding his next assignment from a Shop Assistant (Lucinda Gorringe) inside London's famous Forbidden Planet movie, comics and pop culture store. The gag was the Assassin was getting his information from the shop's UFO & Unexplained department. The scene was eventually cut for pacing reasons, as well as the fact Julian Boote, the story's writer/director, felt seeing The Assassin emerging from the store did the same job. Forbidden Planet has since moved from the Oxford Street location seen in the movie to Shaftesbury Avenue.
Shot in May 2001.
