In a memorable scene from the World War II-era film, her eyes fill with tears as "The Marseillaise" plays, and she cries out, "Vive la France!"
LeBeau died May 1 in Spain after breaking her thigh bone, her stepson, Carlo Alberto Pinelli, told CNN.
According to IMDB.com, there were parallels between LeBeau's role in "Casablanca" and her life. The French actress escaped Nazi-occupied France, fleeing with her then-husband, Marcel Dalio, who also had a role in "Casablanca."
"While the plot of Casablanca traces the movements of European refugees through Morocco, a look at the actors involved in the production also tells a story of émigrés," the Academy of Motion Picture Arts and Sciences noted in a 2014 article about LeBeau and other artists who fled Europe and appeared in the film.
Records indicate that actors from 34 different countries participated in "Casablanca," according to the Academy.
At film's end, Rick manages to ensure that Ilsa leaves with Victor. But having killed the villainous Major Strasser (not pictured), he will need to flee Casablanca, presumably accompanied by the likeable but corrupt police captain, Louis Renault (Claude Rains), who has had an epiphany of his own. In the end, they walk into the fog with Rick uttering the famous last words: "Louis, I think this is the beginning of a beautiful friendship."
She later married Italian screenwriter Tullio Pinelli, whose writing credits included "La Dolce Vita," "8 1/2" and "La strada."
