4. “Play It Again, Sam.”

Casablanca 1942

Casablanca may be one of the most influential and important films of all time, but that doesn’t make it impervious to the Mandela Effect. This one also comes down to a misquote that has since wormed its way into the population’s collective memory. Over the years, it has since been shocking people to learn that one of the film’s most memorable lines isn’t actually in the film, at all.

Play it again, Sam” is one of the most well-known quotes in movie history, and it’s actually not spoken at all in Casablanca. Both Ilsa (Ingrid Bergman) and Rick (Humphrey Bogart) are heard asking piano player Sam (Dooley Wilson) to play “As Time Goes By”, but neither character ever actually utters the words as quoted. Regardless, countless people will attest to the fact that either Ilsa or Rick does indeed say the line, only to discover upon watching Casablanca that the line was never spoken.

Ilsa says “Play it once, Sam“, and Rick says “Play it!”, but neither character says the word “again” in their respective exchanges with the piano player. This particular example of the Mandela Effect is largely attributed to the film’s cultural importance and the passage of time influencing people’s memories of the film. Even so, the misquote is just that, and any memories to the contrary are simply imagined.
