Morrisroe's longest film, Nymph-O-Maniac, tells the story of a portly phone sex operator and her insatiable girlfriends, one of whom comes to a grisly end at the hands of two sadistic young toughs. One of Morrisroe’s three surviving films (a fourth, centered on the murder of his cat, was censored immediately after it was shown, and has been lost) that all engage with the experimental cinematic language of their time, incorporating elements of horror cinema, a punk ethos, and the outrageousness of artists like Jack Smith, Kenneth Anger, and John Waters.
