From The Grindhouse Cinema Database
- Even though Robert Dunham spoke nearly perfect Japanese throughout most of the film, he did get off one phrase of English. In the scene where the mob breaks into his hotel room and Gangster Moll snatches the key to the safe he says in perfect English "Hey, you can't take that".
- There were originally plans to feature Robert Dunham in a series of films based on the character he played in this film. However, those plans never came to fruition.
