“Must a man become a demon just to survive?” wonders the protagonist of Hiroshi Teshigahara’s striking Japanese drama Pitfall (1962). On the basis of the movie, I’m inclined to say yes, though the story unfolds amid such a stark natural landscape that even becoming a demon may not be quite enough. You can judge for yourself tonight at 6:30 PM when Pitfall screens at the Chicago Cultural Center, 77 E. Washington; I’m scheduled to take part in a panel discussion after the movie.
