Inkubo

While theatrical distribution was being sought for the film, actor Milos Milos murdered Barbara Thomason Rooney (also known as actress Carolyn Mitchell, then wife of Mickey Rooney) and then killed himself following Rooney's discovery of their affair. Twelve days before the San Francisco International Film Festival premiere, actress Ann Atmar committed suicide. Two years following the premiere, Marina Habe, daughter of actress Eloise Hardt, was abducted and brutally murdered. The case remains unsolved. Domestic theatrical distribution for the film was never obtained, the film elements were stored away, and the film fell into total obscurity in the US.

The English subtitles are sometimes incorrect. For example, at one point Marc says to Kia: "I want us to be together. To stay together ... as man and woman." This matches the Esperanto dialogue. Then he says, "Mi volas havi infanon." The correct translation: "I want to have a child." The subtitles say: "The right way." He also says, "Mi deziras, ke ni estas kune." Translation: "I want us to be together." Subtitles say, "I want your body ... and I want to give you mine."
