There is a scene where an Asian gang is watching "Nosferatu" (1922) in a private theatre. It is featured prominently in the scene and mentioned by name. The main character Frank White's appearance in black suits, driving around in a black limousine and being active mostly at night can be seen as visual references to the vampire Nosferatu, too. There are also parallels in the basic storyline: Like in
F.W. Murnau's classic vampire film a sinister force suddenly appears and takes over a whole city.
