How long was the pre-production period?   The actors, Jen and John Hawkes (who played Teardrop) came down a week ahead of time. Jen had to do a lot of work learning how to use the farm machinery and the squirrel skinning. John visited some bars and got recordings of people's voices in the community to learn accents. "This was a crucial part of the production, to have time before rolling to get acclimated and steeped and immersed in the groove."
