(I originally shared this film back in 2011, 2019, 2022, and 2023 — can you believe we’ve been doing this for that long? — but the YouTube upload keeps getting taken down! So, I’m resharing it today!)
For today’s excursion into the world of public domain horror, I offer up the film debut of Francis Ford Coppola. Before Coppola directed the Godfather and Apocalypse Now, he directed a low-budget, black-and-white thriller that was called Dementia 13. In a possible sign of things to come, producer Roger Corman and Coppola ended up disagreeing on the film’s final cut and Corman reportedly brought in director Jack Hill to film and, in some cases, re-film additional scenes.
Regardless of whether the credit should go to Coppola, Corman, or Hill, Dementia 13 is a brutally effective little film that is full of moody photography and which clearly served as an influence on the slasher films that would follow it in the future. Speaking of influence, Dementia 13 itself is obviously influenced by the Italian giallo films that, in 1963, were just now starting to make their way into the drive-ins and grindhouses of America.
Speaking of giallo films, keep an eye out for Patrick Magee, who gave a memorable performance in Lucio Fulci’s The Black Cat. Luana Anders, who plays the duplicitous wife in this film, showed up in just about every other exploitation film made in the 60s and yes, the scene where she’s swimming freaks me out to no end. Other films featuring Luana Anders include Night Tide and Easy Rider, in which she played one of the hippies who unsuccessfully enticed Peter Fonda and Dennis Hopper to stay at the commune.
As for Francis Ford Coppola, well, he’s gone on to have quite a career, hasn’t he? It’s been quite a journey from Dementia 13 to Megalopolis!

The year is 1962. Lights flash over California and the news on the radio is bad. What everyone feared has happened. Atomic war has broken out and the world is about to end. Refugees clog the highways as a mushroom cloud sprouts over Los Angeles. This is year zero, the year that humanity will either cease to exist or try to begin again.
