1. The Maltese Falcon was based on a novel of the same name by Dashiell Hamett. Its protagonist, Det. Sam Spade was a chief influence of Raymond Chandler's character Det. Philip Marlowe, who was the protagonist of The Big Sleep. The obvious connect was both were characters played by Humphrey Bogart.
2. That's Bogart as Fred C. Dobbs from The Treasure of the Sierra Madre.
