Bozic in the film twice refers to riderless horses as 'empty horses'. This is likely to be a reference to director, Michael Curtiz, with whom Errol Flynn had worked on 'The Charge of the Light Brigade (1936)'. When wanting to see stray horses wandering through the battle, Curtiz directed the wranglers to "Bring on the empty horses." When David Niven and Flynn cracked up laughing, he responded with: 'You people, you think I know f*ck nothing; I tell you: I know f*ck all". Niven later made this "curtizism" immortal by titling a volume of his autobiography:"Bring on the empty horses."
