Most of the other comments on here are pretty accurate. This movie really showed the loosening up of Hollywood as far as female nudity went. We get to see the beautiful Leigh Taylor-Young in various stages of nudity and looking good dressed too. Ryan never looked better. Lee Grant perfected the role of a perpetually uptight woman in Valley of The Dolls and this seems to be a continuation. The only actress in this movie that really shined was Cindy Eilbacher who could act rings around any other child actor of this or later era. Her few scenes really stand out and almost seem to be from another movie. Loved the cars, the clothes, the great character actors and YES I did love the music but it was all wrong for this movie. I think this music was meant for Dean Martin's last Matt Helm movie with Sharon Tate that never got made. It was lush orchestrated loungy pop music but was all wrong for a crime-noir movie. It really threw me off but I enjoyed hearing it from another room when I wasn't watching the screen. This also has some really great campy lines mainly from Van Heflin calling Leigh a "Quiff" in one scene and various other vague vulgarities. I really enjoyed watching Van go near the edge of camp and then pull back a bit. James Daly was perfect as a high class sleazebag. Look for Ryan's brother Kevin as the passenger in the dune buggy scene.
Overall much better than the horrendous remake, especially if you like movies that are so bad they are good.
