The Psychotronic Film Society’s long-running, award-winning series of overlooked or marginalized feature films from around the world continues with a special 105th Birthday Tribute to the late, great writer, producer, director and actor William Castle. He was known in Hollywood as the “King of the Gimmicks,” for his uncanny knack with marketing his crowd-pleasing films with crazy, provocative promotional schemes.

The genial, innovative movie impresario, made or helped make numerous box-office successes from the 1940s through the 1970s (“The Tingler,” “Mr. Sardonicus,” “House on Haunted Hill,” “The Lady from Shagnhai,” “13 Ghosts,” “Homocidal,” “Strait-Jacket” and “Rosemary’s Baby,” among others). He also frequently appeared in cameo roles in his own macabre productions, and/or introduced the films himself, on-camera - which led to him being dubbed “The American Alfred Hitchcock.” In fact, it was Castle’s immense success with grisly, terrifying fare that led Hitchcock to make what many feel is his signature motion picture, 1960′s portrait of a serial murderer “Psycho.”

The exact title of the William Castle film the PFS will show remains a closely guarded secret right up until showtime. However, this much can be said: it was commercially unavailable for decades, and stands as one of the more divisive titles in his estimable oeuvre. Many of his fans have never even heard of this title, let alone seen it. However, there are also some folks out there who saw it during its brief theatrical release and adore it to this day, despite being basically unfamiliar with the rest of Castle’s career.

Adventurous movie lovers are encouraged to take a chance, buy a ticket and be pleasantly surprised by this restored, widescreen print of a truly odd rarity that must be seen to be believed. Showtime is 8 p.m.
