This was a busy week for actress Pilar Seurat (Pilar). Just five days later on December 22, 1967 she would appear in one of her best-remembered roles: Sybo in Wolf in the Fold (1967).
A Tale of Two Henry's. Henry Darrow (Manolito) and Henry Silva (Castenada) worked together earlier in Tourist Attraction (1963). Interestingly, in a thematic parallel to their roles in The High Chaparral, Darrow played a policeman and Silva played a megalomaniac Latin American dictator.
