Actor Jonathan Hansen grew his beard for more than a month for the role. Director Patrick Clement also grew a beard, in solidarity.
The production took 3-5 hours off in the middle of every shooting day to avoid the mid-day heat of summer and to use beginning and end-of-day sunlight.
While the house and camp appear to be set in the middle-of-nowhere, it was right next to a very busy rural highway. The shooting schedule was arranged to avoid the busiest part of each day.
Filmed entirely on location in southwest Kansas.
