 During one particular scene, actress Andrea Moore was portraying a  junkie and had a real syringe in her hand. Director James McDonald  gave very little direction to the actors involved because he shot  most of the scene with one camera, hand held and wanted the actors  to improvise the scene as it went along. During the scene, Andrea  started freaking out and threatening the other actors with said  syringe (as she was supposed to do) and at one point the elevator  doors opened and people inside didnt know what was going on and  called security. Armed security guards showed up and James had to  explain that they were shooting a movie.
