Raymond Chandler cameo

The embedded image is a screencap from Double Indemnity.

"Moving beyond short stories, Chandler began to write novels. His first was The Big Sleep, published by Knopf and establishing detective Phillip Marlowe as a noir figure. Williams says, “[Phillip Marlowe] was a step forward from the characters of the pulp stories – a fully realized man rather than a vehicle for action.” What differentiated Chandler works from his peers James M. Cain and Dashiell Hammett was the focus on character and setting and less on mystery and plot. Also Chandler’s narrative was in the first person which would later prove to be a strength for noir. Williams calls these elements “the key to his success.” Chandler wrote several novels, most of them featuring detective Marlowe. The biography goes into detail about The Big Sleep, Farewell, My Lovely, The High Window, The Lady in the Lake, The Long Goodbye and others. Most of his novels were initially flops. His first publisher Knopf neglected to market them well, didn’t see Chandler’s true potential. In the end Chandler’s stories proved to have legs in Hollywood and beyond."
