The Man From Earth
This may have been mentioned before but I missed it. It was unknown to me but, apparently, has a cult following so might not be unknown to everyone here. I watched this film last night on Amazon Prime and what a curious film it is. Virtually no action, no special effects, all dialogue and, frankly, bad acting. But it draws you in with its story which I will not expand on in case you haven't seen it. Essentially, it is a one set film and appears to have been adapted from a stage play but the reverse is actually the case.
