Adapted by Norman Foster and John Fante, Flaherty's "The Story of Bonito, the Bull" was based on an actual incident that took place in Mexico in 1908. It relates the friendship of a Mexican boy and a young bull destined to die in the ring but reprieved by the audience in Mexico City's Plaza el Toreo. "My Friend Bonito" was the only story of the original four to go into production, with filming taking place in Mexico September 25 – December 18, 1941. Norman Foster directed under Welles's supervision.
