"Incubus" (1966), a previously lost horror film starring William Shatner, in Esperanto(!)

Directed by Leslie Stevens, who later created "The Outer Limits", and starring William Shatner, it is one of the few films to be made in Esperanto. It was believed to be lost until a print was discovered in France in 1996. There is a lot of folklore about it being a "cursed" film as several people involved met gruesome fates after it was made. Actor Milos Milos died in a murder-suicide (killing his lover, the wife of Mickey Rooney), and actress Ann Atmar also killed herself before the film was released. Arrow Video released a 4K Blu-ray earlier this year, which I bought out of sheer curiosity. It's a very strange film—kind of a cross between Ingmar Bergman and the low-budget AIP Roger Corman films of the '60s. Anyone else seen it?
