Nightflight has a great article about the weird and wonderful cult exploitation 70s movie, Pretty Maids All in a Row, with a screenplay by Star Trek creator Gene Roddenberry!
Pretty Maids would end up being Roddenberry’s first — and only — feature film writing credit during his impressive and long career. He transformed the problematic first draft of Pollini’s original story completely, deepening the dark comedy (it’s pretty black, actually) and softcore semi-misogynistic erotica of the original story — about a high school guidance counselor and football coach who sleeps with a lot of his foxy female students and then murders some of them (the ones who fall in love with him, and ask him to leave his wife, and daughter) — and turning the story into a whodunit that one writer later described as “an episode of ‘Kojak’ written by the staff of Penthouse Forum.“
I also like the opening song by the Osmand Brothers, called "Chilly Winds."
