In his autobiography The Moon's a Balloon, David Niven recalled the kindnesses extended to him by Hollywood's dress extras during Niven's formative acting years. Singled out for special praise was a dignified, frequently bearded gentleman, deferentially referred to as "The Major" by his fellow extras. This worthy could be nobody other than the prolific Major Sam Harris, who worked in films from the dawn of the talkie era until 1964. Almost never afforded billing or even dialogue (a rare exception was his third-billed role in the 1937 John Wayne adventure I Cover the War), Harris was nonetheless instantly recognizable whenever he appeared. His output included several of John Ford's efforts of the 1940s and 1950s. Drawing upon his extensive military experience, Major Sam Harris showed up in most of the "British India" pictures of the 1930s, and served as technical advisor for Warners' Charge of the Light Brigade (1935).
