The quote 'Play it, Sam' is a legendary request from Ilsa Lund in 'Casablanca.' The instrument is an upright piano played by Dooley Wilson. In reality, Wilson was a drummer and couldn't play the piano; he mimicked the movements while a pianist played off-camera. The piano itself became a legend of cinema history, symbolizing the heartbreak and memory of Rick and Ilsa's time in Paris. Its slightly tinny, bar-room sound captured the atmosphere of Rick's Café. In 2014, the prop piano sold at auction for over $3.4 million. This instrument proved that a simple prop can become as legendary as the movie stars themselves, serving as the physical catalyst for a film's most famous quotes and its emotional resolution.
