Rope with James Stewart is a classic.
The Fugitive with Harrison Ford
Dial M for Murder
Zodiac has no reveal but is still a great movie
Wind River is fantastic but also very visceral and hard to watch
Insomnia
State of Play
I know a lot of these aren't the traditional Murder mystery with a large group of people trying to uncover who the killer is, but I do think some of them have the same vibe.
