Michael Findlay, along with his wife Roberta Findlay, directed and produced numerous sexploitation movies. They have been described as "the most notorious filmmakers in the annals of sexploitation". In the mid-to-late 1960s, Findlay was prominent among a small group of underground New York filmmakers (including Joseph W. Sarno, Joseph P. Mawra, and Lou Campa) that produced exploitation "roughies" (a mix of sex and sadism) for the grindhouse theater market. Sometimes he would direct under the alias Julian Marsh and act in his own films billed as Robert West. His wife Roberta (aka Anna Riva) was the cinematographer, co-writer, and supporting actress for many of their films together. They also employed the same actors repeatedly, most notably Uta Erickson, and Marie Brent, aka Janet Banzet. The Findlays were friends with George Weiss, producer of Ed Wood's Glen or Glenda and a series of fetishistic Olga films (Olga's House of Shame, Olga's Girls, et al.). In 1964 Weiss encouraged them to make films in this new subgenre of violent sexploitation.
