Jule Styne wanted Frank Sinatra for the role of Nicky Arnstein, but the actor was willing to appear in the film only if the role was expanded and new songs were added for the character. Ray Stark thought Sinatra was too old and preferred someone with more class like Cary Grant, even though Grant was eleven years older than Sinatra. Marlon Brando, Gregory Peck, Sean Connery, David Janssen, and James Garner were also considered. Egyptian Omar Sharif was cast to star opposite the Jewish Streisand after Wyler noticed him having lunch in the studio commissary. When the Six-Day War between Israel and Egypt broke out, studio executives considered replacing Sharif, but both Wyler and Streisand threatened to quit if they did. Later, the publication of a still depicting a love scene between Fanny and Nicky in the Egyptian press prompted a movement to revoke Sharif's citizenship. When asked about the controversy, Streisand replied, "You think Cairo got upset? You should see the letter I got from my Aunt Rose!"
