A pre-gore Lucio Fulci giallo that, like most of Fulci's films, looks great with plenty of wonderful close ups and weird angles. Unfortunately the story is just plain stupid. It comes off as a take on Hitchcock's Vertigo through both the setting and the doppleganger plot device. But here, after the big reveal, there's no reason at all for the look-a-like other than to have a few scenes take place in a topless bar. The climax is presented as a news report?! Lame. Stupid. Lots of Mod-era stripteasing though!
