Mantis in Lace is very much a product of the late 60s, with the ending of censorship and the freedom to experiment with edgier themes. Released in 1968, this film was probably one of the first color soft-core flicks to be released. The special effects are cheesy, the murder scenes are unconvincing, the dialog is hammy, and the plot is paper thin. But what do you expect? The story centers around a cute dancer, Lila, who has a drug problem. She has sex with guys who naively falls for her. Lila, while hallucinating, murder guys after wards. The murders are then investigated. The sex scenes are mainly non-pornographic with usually only the bare back and sides being shown. The 60s are very much the experimental age with some bizarre-looking hallucination scenes. I call it weird art. There is a cut scene that features an even more bizarre hallucination. And it tops it off with a gruesome gory murder that combines bare breasts, blood, and gore. It is something that was and probably is still too explicit to be shown to normal viewers.
The heart of the film are, of course, the topless dancing featured by three or four young women. They are very nice to watch, even though a couple of the girls are quite ugly. Mantis in Lace will very much remain a part of film history. Overall recommended, if this is your type of stuff.
