The Sleeping Car Murder (1965)

I saw this movie only once or twice -- on cable in the early 1980s, I think -- and it has remained one of my all-time favorites. It is filmed in black and white, and is a French police thriller seemingly populated with good-looking and sexy men, which is always an asset for me. I also love Simone Signoret and she is marvelous in this, as always. I think her daughter is in it, too, but I could be wrong. I cannot really review it because it is more or less a dim memory, but I remember being totally captivated by it. I have always looked out for it, but have not been able to either rent or buy it. I only remember excellent films, and I guarantee that any film buff would find this highly watchable and enjoyable.
