Exclusive ‘Posthumous’ Clip Teases Analog Horror Ahead of Fantastic Fest World Premiere
Josh Tanner is preparing to make his feature directorial debut at Fantastic Fest, and Horror Movies Uncut has an exclusive look at Posthumous ahead of its world premiere in Austin.
The supernatural horror film will make its world premiere Saturday, Sept. 19 at 2 p.m. at Alamo Drafthouse South Lamar as part of Fantastic Fest 2026.
Tanner, whose previous work includes the shorts The Landing and Wandering Soul, moves into feature filmmaking with a mystery rooted in family history, grief and the unsettling possibilities hidden inside old technology.
Posthumous follows Zoe after she returns to her childhood home and discovers a mysterious videotape. What she finds on the recording begins challenging everything she believed about her birth and the death of her mother, eventually opening the door to something far more disturbing.
The exclusive clip offers audiences a glimpse at the film’s use of analog imagery and recorded media, elements that become increasingly important as Zoe attempts to understand what happened before she was old enough to remember it.
Rather than treating the videotape simply as a retro horror device, Posthumous places the technology at the center of Zoe’s search for answers. The recordings provide a connection to people and events from her family’s past while gradually raising new questions about exactly what has been preserved on them.
Tanner co-wrote the film with Jade van der Lei.
The cast includes Gabriel Cagan, Georgia Kate Haege, Madeline Barbush, Estevan Muñoz, Kaoru Koide, Takumi Mitobe and Daniel Berkey.
Tanner arrives at Fantastic Fest after building an audience through his short-form filmmaking. The Landing and Wandering Soul have accumulated millions of views on YouTube, with Posthumous representing his first opportunity to expand his approach to genre storytelling into a feature-length production.
The film also arrives as analog technology continues to provide fertile territory for contemporary horror. VHS tapes, camcorders and physical recordings offer filmmakers more than nostalgia. They represent memories that cannot be easily changed, deleted or explained away, making them particularly effective when a character begins discovering that the past they remember may not be the past that actually occurred.
For Zoe, that investigation becomes deeply personal.
Her discovery is not simply about uncovering something strange on an old tape. It threatens her understanding of her mother, her birth and ultimately her own identity, placing a family mystery at the center of the film’s supernatural horror.
Horror Movies Uncut has already had an opportunity to see Posthumous ahead of Fantastic Fest, with our review finding Tanner’s debut particularly effective when combining its analog unease with Zoe’s grief and need for answers. The film’s turn-of-the-century technological atmosphere recalls an era of horror when videotapes, recordings and emerging technology could make the distance between the living and the dead feel unexpectedly thin.
Now Fantastic Fest audiences will have their first opportunity to experience it on the big screen.
Posthumous makes its world premiere Saturday, Sept. 19 at 2 p.m. at Alamo Drafthouse South Lamar during Fantastic Fest 2026.
