OK, But Where's the Priest?

Linda's Film on Menstruation

Mady Heflin (daughter of Frances Heflin and Sol Kaplan and sister of director Jonathan Kaplan) plays a teenage girl riding her first menstrual cycle in Linda's Film on Menstruation (director Linda Feferman is also responsible for Seven Minutes in Heaven); character actor Jonathan Banks (he played the attendant who confiscates Dr. Lizardo's TV in Buckaroo Banzai) is also along for the ride.

This 1974 educational film, missing a few frames in the beginning, features attempts at humor, an unfocused plot, animation, person-on-the-street interviews and the Statue of Liberty — a mess, so yes it's really great.
