I haven’t seen this one, only read about it in a post on 366 Weird Movies. It was probably not part of the official list or apocrypha, and may have been a short/less than feature length.
From what little I recall, it sounded like a quasi-Western shot in desert-type locations, with a very small cast. There were oddly low-budget choices, like cheaply home-printed or even handwritten crossroads signs, and inexplicable anachronisms such as someone presenting a credit card to pay for lodging.
In spite of remembering these specific details, I don’t seem to be phrasing anything correctly for the search engine at 366 to dig up my answer. Still trying, though. In the meantime, does this ring a bell for anyone?
