So far my Hardboiled Hangover foray into the world of film noir has turned up some pretty paranoid pictures. Typically these disquieting films were reserved for the late WWII period and the post-war years when several factors led to an anxious nation. So where the hell did Boris Ingster’s 1940 pitch black thriller Stranger on the Third Floor Come from?! This is one dark sonsabitch spearheaded with disturbed performances from John McGuire and the almighty Peter Lorre, and some of the most striking cinematography I’ve seen in a while. Who’s the Stranger on the Third Floor? Short answer: one creepy ass dude. Long answer: hit the jump.
