未亡人 未亡人変態地獄 (1991)

　　Hisayasu Sato is famous for his "guerilla shooting technique" in which his actors appear on location in public and incorporate unknowing bystanders into the film. One notorious example of this technique can be seen in Widow's Perverted Hell (1991) in which the lead actress, nude and bound in S&M gear, appears in a busy downtown location and begs confused passers-by to help her masturbate. All Movie Guide comments, "Like Divine's memorable strut through the streets of Baltimore in Pink Flamingos, this scene was shot guerrilla-style, with no advance planning, and some of the reactions from unsuspecting pedestrians are absolutely priceless. Intended as a dark meditation on the unhinging effects of grief, the mondo aspects of its climactic scene makes the rather lackluster Mibojin Hentai Jigoku worth seeing."
