Surely Anthony Mann and John Alton were a great team, but it should be pointed out that production designer William Cameron Menzies also had a great influence on the visual style of this forgotten gem. Just look at those bare walls decorated just with muskets. http://p4.storage.canalblog.com/41/19/110219/76317890.png
I agree with reviews below that point out what an intriguing mix of noir and period piece this is. Plus, the team of Anthony Mann and DP John Alton team up to once again produce some of the starkest, most haunting cinematography of the era. A unique film and definitely worth seeking out.
