10 Horror Movies You'll Probably Never See
8. Sin-Jin Smyth

Sin-Jin Smyth is a supernatural horror film set in a dystopian America that has descended into an authoritarian police state, as two federal marshals find themselves dealing with the emergence of Satan.
Ethan Dettenmaier's picture had quite the unique and diverse cast, including Richard Tyson, Halloween star Charles Cyphers, wrestlers Rowdy Roddy Piper and Jacqueline, Korn vocalist Jonathan Davis, and The Cult guitarist Billy Duffy. Furthermore, it had a not insignificant budget of $14 million, and was initially due to release in 2006.
However, the film was continually delayed, and doubts soon emerged about precisely how much of the project had actually been shot, even with seven minutes of footage landing online in 2008.
Some have suggested that the filmmakers lacked sufficient funding to complete all aspects of post-production, with actress Eileen Dietz later claiming that Sin-Jin Smyth is never coming out.
The late Roddy Piper was also frustrated that the production continued to use his name for promotional purposes without having a finished film, and given how little we've heard about Sin-Jin Smyth over the last decade, it's clear that it's never going to release, no matter how much of it was actually shot.
