When I was researching it afterward, however, I found out that they used NO CUTS. That's right, one hundred percent done in one take. It only took them 3 attempts to make an entire movie using mostly natural lighting and their few locations. Knowing now it now makes sense why the story seemed to drag at points - there was no way that improved dialogue would have the pacing expected of a feature script.
Absolutely amazing job, I highly recommend you see this film when it is released.
