Just finished watching TCM's Eddie Muller's "25 noir films that will stand the test of time." Ask me anything.

Not a documentary, but 25 actual films. Took a while. It's a blast.

Says Muller: "Take this with a grain of salt, because I am not one to apply academic criteria to art, popular or otherwise. These are simply films that I have viewed and enjoyed multiple times, and expect to appreciate even more as time goes on."

"A "classic" is in the eye of the beholder anyway; to me there's only one way to assess a film's greatness—is it still engrossing the sixth time you've seen it?"

Muller's 25, in order of release:

The Maltese Falcon (1941)
Double Indemnity (1944)
Scarlet Street (1945)
Detour (1945)
The Killers (1946)
Out of the Past (1947)
