There was entire blocking sequence planned around a stone statue on Swarthmore Ave that was completely removed when the crew arrived on location, forcing them to improve new blocking.
The entire film was shot in approximately 2 hours. The editing process was 5 hours. And the entire production, concept-to-celluloid, was four weeks.
The Dom Perignon bottle seen in the film actually exploded in the car ride to the location unbeknownst to the filmmaker, which is why the liquid is completely flat in the final shots. But it was genuine 2006 Dom Perignon.
