Just how weird is “The Greasy Strangler”? Let’s take a minute.

It’s about a chubby man-dweeb named Big Brayden (Sky Elobar), who suspects that his elderly, irascible father, Big Ronnie (Michael St. Michaels), moonlights as the Greasy Strangler, a creature who covers himself (and his mega-penis) in oozing layers of grease and fat before he sets out to slaughter. By day, the two men lead tours of supposed disco landmarks. They dress in gender-warping outfits that a generous fashion critic might call the Willy Wonka collection for Chico’s. When they fall in love with the same bodacious woman, Janet (Elizabeth De Razzo), it sparks a Jerry Springer-meets-Arthur Miller war of sexual and emotional duplicity.

The film, which opens Oct. 7, overflows with extravagant flatulence, frenzied gore and preposterous copulation. Or as Variety put it: “an exercise in juvenile scatology that’s almost awesomely pure in its numbing, repetitious determination to annoy,” with a “sense of absurdism that stubbornly remains on the peepee/caca level.”

So, yeah, it’s that weird.

Those words are sweet nothings to Jim Hosking, the director of “The Greasy Strangler,” which had its premiere at Sundance. Mr. Hosking said he found inspiration for his feature debut in the mysteriously artful films of David Lynch, the punk-inflected 1980s British sitcom “The Young Ones” and “filmmakers who are distinctive and different and who go their own way.” The result, he said, was “a really unfiltered script, something that was perfectly self-indulgent and pushed various ideas of comedy.”
