Venus in Furs, by Jesus (Jess) Franco, is pretty good. It's about a jazz trumpeter, played by James Darren, who finds a naked, dead woman washed up on the beach, and then things get weird.
It seems that Jimmy Logan recognizes the dead girl as Wanda Reed (Maria Rohm). In fact, he dimly recalls her murder - or did he dream it? Or is he dead himself? Welcome to 1969, where apparently this kind of hazy reality was, like, a reality.
Sometime after finding Wanda's body, Jimmy runs into...Wanda. Wait, isn't she dead? Who knows, man, but next thing anyone knows, the gang she was hanging with is joining her in the thereafter. Guys like art dealer Kapp (Dennis Price) and fashion photog Olga (Margaret Lee) and Klaus Kinski. Well, someone played by Klaus Kinski, but either way, weird.
Meanwhile, Jimmy's falling hard for Wanda, who - again - is probably dead. He likely isn't, because he has a girl named Rita (Barbara McNair), a singer in the combo wherein he jazz trumpets. And Rita can see Wanda, so it's not like Wanda appears only to Jimmy. So maybe Rita's dead too. It's not really important.
Visually speaking, this isn't a bad effort. And the score, particularly the jazz, is really cooking. James Darren isn't a bad actor. Also helping? The multiple naked women. I mean, they're in almost every scene.
