The rare U.S.-lensed giallo includes San Francisco settings and less violence than the norm, strengthening the story’s nods to Vertigo. Is head-turning stripper Marisa Mell the woman she appears to be, or is she the thought-to-be-dead mousy wife of doctor Jean Sorel? His mistress Elsa Martinelli, his sister-in-law Faith Domergue (once groomed for stardom by Howard Hughes), and detective John Ireland want to know. Scored by Riz Ortolani.
