When BCI Eclipse obtained the rights to release Blood Song on DVD, they could not find any original elements or prints to transfer. This means the original elements and prints either no longer exist or are temporarily lost. BCI was then forced to use a video source to transfer instead.
One of the film's writers and co-producer Lenny Montana, a one-time pro wrestler and ex-mob enforcer-turned-actor, played Luca Brasi in The Godfather a decade earlier. He appears here in a small role as a mill boss, cast alongside his own son (Lenny Montana Jr.) as the truck-driver victim.
Blood Song was produced and distributed by the small independent outfit Summa Vista Pictures (headed by Avianca and Montana) in 1982, who then handled the film's U.S. theatrical run and initial video licensing. Over time, as is common with low-budget 80s films, the rights changed hands or lapsed. As of 2025, the current ownership of Blood Song remains somewhat unclear publicly. There is no known active distributor - the film is not owned by a major studio - and it appears to be in a kind of rights limbo. It's likely the copyright is still held by the original producers or their estates, unless it was sold off. Industry discussions hint that any attempt to re-release Blood Song now faces hurdles such as "complicated rights issues" or lack of a willing rights-holder. In short, no company is currently publicly claiming distribution rights, and the film is absent from legitimate streaming platforms - thus leaving Blood Song in distribution purgatory.
Shot on location in Oregon and features landmarks around Coos County (the Southsider Motel, a local hospital, etc.), which still exist decades later. The climactic chase was filmed in and around a real sawmill.
Fifties teen idol Frankie Avalon, known for beach party movies and his wholesome image, was cast as the killer. According to accounts, the film's producer Lenny Montana got the idea after seeing Avalon play a darker role on an episode of Fantasy Island, and reached out to him for this against-type role.
