The Legion of Missing Men is a 1937 Monogram Pictures film about the French Foreign Legion set in the French protectorate of Morocco. Directed by Hamilton MacFadden, it stars Ralph Forbes who had also served in the cinematic Foreign Legion in Beau Geste (1926) and Beau Ideal (1931). Singer and actress Hala Linda was married to Richard Gump, the composer of the film's "The Legionnaires Song". It was the only film of Monogram's Marlene Dietrich imitator. The film features scenes reused from a silent film, presumably Under Two Flags.
