Not only is this one of the top films in the genre, but it was very cutting edge for it's era. Directed by Otto Preminger, who was really pushing the boundaries with this film, it contains great performances from Stewart and Lee Remmick is stunning as the super-flirt wife. The dialogue just sizzles, on the level of Bogart and Bacall. And as if that wasn't reason enough to watch it over and over again, the soundtrack is stunning, written by Duke Ellington, it is the essence of moody gumshoe jazz and swing. I had to buy the soundtrack as well! And it's the best CD to play when you are in a dark mood! That aside, this is an essential, whether you are a Preminger fan, a Hitchcock buff, or even just a jazz fan. Stunning film, and at that price worth buying your mum a copy so she can drool over Jimmy Stooowart.
