The final entry in the film's closing credits consists of the words "For Herbert". Herbert Wong was Tom Dong's real name.

Near the end of the film when Steven Driver is obsessively watching a film while Eric and his staff try to get him to leave, it's shown that the film is an Asian martial arts film. In reality, he was watching a film before he went on his lethal and bloody rampage, but it was the 2005 film "Kingdom of Heaven" and he kept watching a scene involving a brutal and gore-filled battle.
