Ok, I'll start. To be honest, I've gotten pretty bad about book reading during the pandemic (a combination of losing the commute that I used to squeeze my leisure reading into and my work hours getting terrible), but I did get back in the habit recently, racing through two very enjoyable books about cult cinema.
These Fists Break Bricks: How Kung Fu Movies Swept America and Changed the World by Grady Hendrix and Chris Poggiali, as you can guess, is about martial movies and their place in American culture. Hendrix used to write the Kaiju Shakedown column for Film Comment about Asian genre cinema, and the book combines his enthusiastic writing style with a maddening amount of research (although he's admitted in an interview that some of the subjects the book touches on he only scratched the surface of). A great mix of film appreciation and social/cultural context. There's a sidebar on Bruceploitation, one of the wackiest sections of the book (and probably one of the wackiest genres in cinema) that inspired some of my recent watching, although I have nowhere near Hendrix and Poggiali's stamina in exploring the subject.
Sleazoid Express: A Mind-Twisting Tour Through the Grindhouse Cinema of Times Square by Bill Landis and Michelle Clifford is an extension of the zine of the same name that Landis used to write in the '80s (and briefly revived in the 2000s) about grindhouses in New York's 42nd street and the movies that played in them. I've never read the original zine (although I have a PDF of the original run that was posted to Twitter by a guy who wrote a biography of Landis recently), but the book is a very entertaining mix of film appreciation with vivid "you are there" gonzo-ish depictions of the settings these movies played in and the reactions of the crowds. I understand Landis' editorial standards haven't always been up to snuff (in one of his more notorious articles in the original zine, he supposedly fabricated a story about a crime committed by roughie director Phil Prince, although to be fair, Prince was kind of a scumbag; in the book, he miscredits a pseudonymous role in an Ilsa sequel to Spalding Gray), but the book is a very entertaining read nonetheless. Like with the above book, I've been noting down recs, and probably the one in the book most tailored to me is Patty about a ripped from the headlines hardcore porn movie about the Patty Hearst that started shooting before Hearst was even released (they hastily shot an ending after her release). Alas, this doesn't seem to be on Letterboxd, and from the IMDb page, I'm not sure it's ever gotten a DVD release (although apparently the rights were sold to a DVD company). Paging Vinegar Syndrome.
