The 'K' is actually crushed peppermint mints. There was uncertainty on set as to whether it would be safe to
'snort' or not so Anthony tried it first before the actors agreed to do the scene.
Both the actors, Anthony and Rodd (D.O.P.) spent a week in rehearsals prior to shooting working on
improvisational scenes using scenarios Anthony had encountered throughout his life. The script was written during these improvisational rehearsals.
The location belonged to a friend of Anthony's who also provided the catering for the film.
An alternate ending included 'Ryan' (played by Anthony) laying on the floor with Andreas & Carl in the toilets.
