Mantis in Lace is a very mixed bag. You would think that a sexploitation / mad-slasher movie combined with the LSD subculture of the 60's would be a great idea -- and it is. But nearly half of this movie consists of extended scenes of strippers performing in the club or "trying out" on the casting couch. One can't help but feel that they only had enough time and budget to shoot half a movie and needed to pad it to get to a feature length running time.
With that said, the scenes where Lila trips out on acid and kills her prey are outstanding. Laszlo Kovacs was the cinematographer and it's easy to see that he would go on to shoot such classics as Easy Rider and Five Easy Pieces. Susan Stewart is a remarkably bad actress who can't deliver a line to save her life or even pass herself off as a mediocre stripper. But she's very cute and she has a certain charm that prevents her lack of talent from completely ruining the movie.
The DVD presentation of the movie is in full frame (1.33:1). The picture quality is outstanding for a 35 year old low-budget movie. The outtakes are actually longer than the movie itself, and it appears that there may have been a version of this movie that was far bloodier the the final cut that's presented her.
There are three short films on the DVD as extras, two of which are great time capsule relics from the 60's. "LSD: Trip or Trap!" is a 19-minute film produced by the Inglewood Police Department to warn youth of the dangers of LSD. It's sort of a 1960's version of Refer Madness. The second, "Alice Goes to Acidland", is a 12-minute nudie acid trip that almost defies description.
