Showtime is 8 p.m., with $7 admission, and discounts on craft beer and organic wine during the movie.

The Psychotronic Film Society’s ongoing Wednesday night series of underappreciated, indie, foreign and cult movies at The Sentient Bean continues with a rare public showing of the criminally unknown yet highly influential 1953 sci-fi flick “Invaders from Mars,” timed to coincide with the 64th anniversary of its initial theatrical release. Directed by William Cameron Menzies, this independently made feature was shot in the little-used SuperCinecolor process, resulting in a surreal, otherworldly look to its tale of a young boy who accidentally witnesses a flying saucer crash-land and then becomes convinced that many adults in his small town are being manipulated by aliens from Mars with sinister intentions.

An oddly ambitious and somewhat subversive film masquerading as low-brow drive-in theater quality entertainment, “Invaders from Mars” has sadly fallen through the cracks into relative obscurity, yet is well-known and well-regarded among serious sci-fi and cult movie aficionados. The PFS will show perhaps the best quality print of the original American cut of the film known to exist.
