One of my favorite old film noirs, but mostly because of all of the genres it weaves into its narrative. At the heart of the movie is a sci-fi story that doesn’t reveal itself until you’re nearly finished with the film. You know there is something shady going on, but for the longest time it seems like a standard mystery with the characters going after something they shouldn’t - something the government is trying to get its hands on. There’s an element of danger that propels the movie forward and not even the viewer knows how dangerous the situation is. The ending is left open. How bad is this thing they’re chasing? How much can it destroy? Will anyone be left? I love it.
