Miles is killed and Sam is suspected of murdering him. In search for the truth, he gets tangled up with rival gangs
on the trail of the Maltese falcon, a valable gold statue.
Then Spade contacts a group of colorful criminals; The obese leader Kasper Gutman (Sydney Greenstreet; the perfumed Dr. Joel Cairo (Peter Lorre); and a short-fused gunsel named Wilmer Cook (Elisha Cook, Jr.). Using his wits, Spade expertly turns the conspirators against each other, eventually learning the true killer of his partner.
Keep that gunsel out of my way
Lose a son
Poking the fire again
The cheaper the crook
The stuf that dreams are made of

Mary Astor: “I have heard people say [Bogart] wasn’t really a very good actor. I don’t go along with that. It is true that his personality dominated the character he was playing-but the character gained by it. His technical skill was quite brilliant. His precision timing was no accident” Source / More (Book)

Many film critics believe that The Maltese falcon was the first film noir.
The stories was already filmed in 1931. For decades, this film could not be legally shown in the USA because of the rather extensive use of sexually suggestive situations.
Sam Spade: “Why d’ya let these cheap gunsels hang around the lobby with their heaters bulging in their pockets?”. Writer Dashiell Hammett used the slang word Gunsel. Studio censors okayed the word because they thought it meant gunman. But in the thirties a gunsel was a young homosexual male (Wilmer Cook), especially one who was the companion of an older man (Gutman). Source / More (Web)
