Bloody Disgusting and SCREAMBOX are bringing two horror movies to theaters on the road to Halloween, kicking off with the werewolf comedy Shaky Shivers on September 21.

And then there’s Onyx the Fortuitous and the Talisman of Souls, a practical-effects heavy horror movie that just debuted its official trailer (via Movieweb) this week.

Today, Bloody Disgusting is serving up a retro VHS trailer for Onyx the Fortuitous and the Talisman of Souls, which channels the throwback vibes of this gateway horror delight.

Check out the VHS variant trailer below!

The buzzed-about horror-comedy will be released exclusively in theaters for a one-night event on October 19, via Fathom Events. The film will show at 7:00pm & 10:00pm (local times) in theaters throughout the country, and fans will be treated to a special introduction from writer/director/star Andrew Bowser ahead of the film. 

Based on Bowser’s viral internet character of the same name, Onyx tells the story of an amateur occultist who learns that sometimes when you raise HELL…you get a little burned.  

In the film, Onyx is struggling to find purpose with his soul-devouring side gig when he receives a coveted invitation to the mansion of his idol, Bartok the Great. Here, he joins Bartok and his mysterious delegation to raise the spirit of an ancient demon for a once-in-a-lifetime ritual. 

“Misunderstood by all who know him, Marcus J. Trillbury (Bowser), aka Onyx the Fortuitous, is struggling to find purpose in his soul-devouring side gig. But just when it seems he’s ready to throw in the towel, he receives a coveted invitation to the mansion of his idol Bartok the Great (Jeffrey Combs; Re-Animator) for a ritual to raise the spirit of an ancient demon. Ecstatic, he joins Bartok, his mysterious delegate Farrah (Olivia Taylor Dudley; “The Magicians,” Paranormal Activity: The Ghost Dimension) and a collection of fellow devotees as they prepare for the ceremony, but quickly it becomes apparent things are not what they seem. As Onyx and his new friends fight to keep their souls, he must decide what he’s willing to sacrifice in order to meet his destiny.”

The film also stars Barbara Crampton (You’re Next, Re-Animator), Ralph Ineson (The Witch, The Green Knight), Rivkah Reyes (School of Rock), TC Carson (Final Destination 2), Arden Myrin (Insatiable, Shameless) and Melanie Chandra (Code Black).
