The original plot line had the Bartender shining Josh with a flash light, making him disappear to re-live the scene. This was cut when it was realized that there was not enough footage to make this effect understandable. The entire plot was changed to reflect the rough edit's flow.
The entire film was conceived, shot, edited, and mastered in under 48 hours.
The main location, the bar, was only open for shooting for 4 hours, all footage was shot in that time, the b roll shown was shot after the crew realized they didn't have enough and went back during business hours to shoot the rest.
Most close up shots of the Bartender are actually the hands and back of the Gaffer, Andy Sipe.
