The scene where Joe and Helen share a drink was actually shot on two separate days at different times on the shoot, as the actors playing the two parts (Steve Lofthouse and Riana Husselmann) weren't available on the same day. In Joe's shots, Helen's hand is played by Assistant Director Nikie Hobson; for Helen's shot, Joe's hand is provided by B-Camera Operator Kevin McDonagh.
In the scene where Dodge (Danny Sunley) is playing with nunchak's, the director was laughing so hard he had a nose bleed on set.
