Bad Biology

Bad Biology follows two young people whose unusual biological conditions drive them toward extreme sexual encounters. Jennifer, born with multiple clitorises, pursues men until the encounters prove fatal, afterward giving birth to fast-growing monstrous infants. Batz, shy and equipped with an oversized penis, is searching on his own. Neither knows the other exists until a meeting brings them together in a sexual episode with catastrophic consequences, played out largely in an old twenty-two-room mansion in Brooklyn.

Frank Henenlotter directed and co-wrote the screenplay with R.A. Thorburn, who also produced under the name R.A. the Rugged Man. The film is the fifth feature Henenlotter directed, arriving eighteen years after his previous one, Frankenhooker, and continuing the low-budget horror-comedy territory of his earlier work. Charlee Danielson plays Jennifer, Anthony Sneed plays Batz, and the credited cast runs to fifty-seven people, with forty-four credited crew members.

Released in 2008, the film runs eighty-four minutes. On IMDb it holds a rating of 4.7 from around five thousand votes; on TMDB it sits at 4.6 from roughly one hundred fifty votes. The two audience scores are close, indicating a small but consistent viewer response rather than a sharply divided one.
