"One of a kind" doesn't even begin to describe this feverish underground concoction from Curt McDowell, a San Francisco painter turned director whose unabashed celebration of sexuality gets filtered here through a script by experimental legend George Kuchar packed with gothic horror, absurdist comedy, explicit sex of every legal persuasion, and sweaty melodrama. It also boasts the distinction of being one of the longest-gestating titles in home video history, with the late McDowell's sister, Melinda (who acted in this and several of his other films), announcing a special edition DVD via a website back in 2003. (The only possible record breaker would be Code Red's The Farmer if that ever comes out.) It wasn't until 2015 that we finally got this much-requested title in its first genuinely authorized release courtesy of Synapse, packed with extras offering some much-needed context for a midnight movie unlike any other.

are Sash (Melinda McDowell), the voyeuristic Toydy (Johnson), Roo (Benson), Bond (porn veteran Scudder), and last and strangest of all, Bing (Kuchar), a circus trainer now embroiled in a dangerous carnal relationship with his gorilla, Medusa (played by "Pamela Primate" in a furry suit). Sexual experimentation and dark secrets both consume the evening as the truth about Gert's husband and mysteriously absent son is revealed, and everyone's sexual psychoses resolve in one way or another.

of thing that could have only been made in the mid-'70s and is likely the only thing you could describe as what might happen if John Waters, Guy Maddin, and Radley Metzger had a lost weekend in someone's country house.
past versions. The full 10-minute intermission is reinstated here as well (a
shorter version was included on that one VHS release in the U.S.). The DTS-HD MA mono track on the Blu-ray does what it can with the original audio, which has always sounded awful due to the tinny original dialogue recording (most of it using on-set production audio) and an aggressive sound mix loaded with piano-heavy music and exaggerated sound effects by frequent McDowell collaborator Mark Ellinger (who also starred in McDowell's nutty 1972 adult film, Lunch, and cameos here as the late Mr. Hammond). Thankfully Synapse has provided optional English subtitles (which come in very handy during some of the more cacophonous scenes) and additional ones in French, German, and Spanish. A second audio track features a 1972 interview with McDowell and an unnamed interviewer, providing a very cheerful and detailed walk for 85 minutes through his creative career and process from his early days as a painter through the epiphany that led to his switch to award-winning filmmaker. 
anyone who's seen his more recent video work. He chats quite a bit about working with former student McDowell (who also acted in Kuchar's The Devil's Cleavage), the writing process, and how he wound up playing the part of Bing (which he originally envisioned for a totally different physical type), for which he provided his own "protuberance" for one unforgettable scene. Next comes a pair of additional featurettes crafted in 2004, presumably for the DVD's initial release announcement, with Eaton sitting in a park for a 5-minute diary remembrance of her favorite bits about playing Mrs. Hammond and Ellinger (who now focuses on San Francisco history and architecture) offering an 8-minute recollection of his McDowell days including multiple duties on the set of Thundercrack! He's especially candid about the film's ill-fated theatrical history, offering some much-needed chronology for how it was released. A local public access show called San Francisco Bay Area Filmmakers comes next with a 23-minute interview with McDowell and Eaton talking about the creation of Thundercrack! and their thoughts about explicit sex on the screen, including some revelatory comments about how McDowell and Ellinger intended it to be a projection of their fantasies before it turned into a more psychosis-riddled art epic in Kuchar's hands. ("We wanted to take something like The Donna Reed Show and make it X-rated!")
footage: a 29-minute reel of regular behind-the-scenes material and alternate or longer takes (including a really fun shot of the cast and crew at the end in the kitchen) and a pretty astonishing 17 minutes(!) of sex scene outtakes, which leave nothing to the imagination but also provide an amusing idea of how
much dialogue was actually looped in later during those sequences. An 8-minute reel of audition footage features most of the cast members doing screen tests both with and without clothing, along with several other hopefuls who didn't make the cut; the fashions and hairstyles alone in this one are truly priceless, while the casual and cheerful sexuality on display is a disarming look at the attitude that carried over onto the set. Finally the disc rounds out with five of McDowell's short films (just a sample of the 30-plus he made during his lifetime). "Confessions" (1972) starts off with McDowell directly addressing the camera for a frank catalogue of his sexual development and experimentation in his youth but midway through turns into an abstract barrage of on-the-street interviews, nature footage, and fleeting sex shots. The visual collage of "Naughty Words" (1972) features Curt and Melinda rattling off both real and imaginary obscene terms for human genitalia over an assortment of smut magazines turned into visual art, while the unabashed "Loads" (1985), his final short, offers a snapshot of McDowell's sexual proclivities as he presents filmed records of a handful of straight male pickups with his voiceover documenting their personalities and life stories. (In the Kuchar doc, John Waters remarks that he can't believe McDowell released this one and calls it "a succession of bad nights," which just about sums it up.) The most chaste of the shorts, "Boggy Depot" (1973), is in many respects the most fascinating as it anticipates both the artificial settings and animated lightning of Thundercrack! and the musical quirkiness of his last feature, Sparkle's Tavern, with the cast singing and rhyme-speaking their way (usually off key) through a surreal, comic story about a collection of characters including a lovesick débutante (Ainslie Pryor) pining for her runaway boyfriend and a pair of "Mean Brothers" (Ellinger and McDowell) who have mesmerized the hapless George (Kuchar) into expressing his love through unorthodox means. Last up is the "The Siamese Twin Pinheads" (1972), a short and raucous burlesque sketch with a nun presenting an increasingly obscene musical performance by the title characters played by a hilariously shameless (and very un-PC) McDowell and Ellinger. A surefire contender for release of the year, at least if your sensibilities are warped enough to appreciate it.
