The Japanese characters on the outside of the meeting room where Kobayashi is talking with Edie Finneran and others say "Kobayashi" and "bengoshi" (attorney); the ones in reverse on the window read "seikou" (success), "chikara" (strength), and "zaisan" (assets).
The idea for this movie started only with the concept of a movie poster of five men in a lineup.
Christopher McQuarrie had previously worked for a detective agency, and this influenced the depiction of criminals and law enforcement officials in the script.
Shot on a budget of $6 million over a period of 35 days.
