Ausgeflippt (1977)

Gay hair stylist Robin Turner does a lot of work for drag queens, all the while dreaming that he'll someday find the courage to perform in drag himself. When his schizophrenic friend, Liza, turns up looking for a place to stay, the two form an increasingly tight bond, Robin helping Liza through an unplanned pregnancy and Liza pushing Robin to develop a successful nightclub act.
