By the time the war ended, $20,000,000.00 worth of war bonds would be purchased through the studio, the Red Cross collected 5,200 pints of plasma from studio employees, with 763 of the studio's employees, as well as Warner's son-in-law Milton Sperling and nephew Jack Warner Jr., would be recognized with having the honor of having served as in the armed forces. Following a dispute over ownership of Casablanca's Oscar for Best Picture, head producer Hal B. Wallis broke with Warner and resigned from the studio.
