For Crypticon this year, I moderated the panels on 1976 horror and 1986 horror. Thanks to the panelists for their great contributions, in addition to anyone who attended or suggested titles. If you see any key films missing, please feel free to let me know.
Due to the timing of the 1986 panel, I missed Tony Kay's interview with Adrienne Barbeau, an actress of whom I've been fond since her days on '70s sitcom Maude; our panel was fun, but that was still a bummer.
In alphabetical order, plus directors, notable cast, and a few notes. If I watched the film online, I've noted the streaming service in brackets.

I didn't do any crowd-sourcing for the list above, but I did for the list below. I also found Kier-La Janisse's House of Psychotic Women helpful (I have the 2022 expanded edition). It's how I discovered the Polish film I Like Bats (Lubię Nietoperze), which I highly recommend to anyone looking for a funny, sexy, quasi-feminist take on the vampire myth. Janisse also included the film in her Severin boxed set House of Psychotic Women: Rarities Collection.
I follow a number of film critics on Bluesky, and Odie Henderson and Norm Wilner were both so enthusiastic about Night of the Creeps, that when I put out a call for 1986 horror recommendations, they shared their excellent reviews. Click their names for more. Sadly, I also missed the interview with star Tom Atkins, who is perfection in the film, because I was on the Pets in Horror panel. Granted, that was a fun one, too, and you can't do it all.
