He’s back! Frank Henenlotter, infamous director of the trash classics “Basket Case” (1982), “Brain Damage” (1988) and “Frankenhooker” (1990) — has released his first movie in years.

It’s “Bad Biology,” and it dispels any sugges tions that time might have mellowed him. The movie concerns the adventures of Jennifer (Charlee Danielson), an oversexed young blonde born with seven clitorises — “that I know of,” she adds.

This means that what she calls “my strange little deformity” keeps her constantly in heat. Doctors call Jennifer a “freak of nature,” but she considers herself “an evolutionary leap forward, the woman of the future who feeds on orgasms the way you people devour burgers and fries.”

Her life gets even more interesting (if that’s the right word) when she meets an oversexed stud, Batz (Anthony Sneed). This being Sunday, the Lord’s Day, I’ll spare you the details.

Danielson, a musician and model making her screen debut, spends a large part of the movie having sex, which requires her to fake orgasms that might register an 8.0 on the Richter scale.

She also gives birth to mutant babies (think “Eraserhead”) two hours after they’re conceived.

Surprisingly, Danielson — who is six months pregnant in real life — says her on-screen work was no big deal.

“The method of acting I do really helped me,” the 26-year-old told me over the phone last week. “I was using pure emotion there. I was just very easy actually, just channeling off that energy. Everything kind of came on its own. It was pretty cool.”

Danielson, who grew up in a conservative Catholic household, says her parents haven’t seen the film and probably won’t. Even her boyfriend is in the dark.

“I feel completely comfortable with [the movie], but they wouldn’t understand . . . I’m going to have to do more conservative things for everybody to look at.”

“Bad Biology” unreeled at several festivals and has just been released on DVD, via Media Blasters.

* Gary Lucas, the West Village’s guitar virtuoso, has two shows on tap. On Friday at 7 p.m., at the Rubin Museum of Art, he’ll perform his original score to accompany “The Golem,” the 1920 German silent considered a “Frankenstein” forerunner.

And at 8 p.m. Feb. 9, at the Gershwin Hotel, Lucas will perform his solo guitar arrangements of film music by Nino Rota, Bernard Herrmann and others. Details available at garylucas.com.
