Legion of Missing Men was one of three Monogram "specials" produced in 1937 by I. E. Chadwick. Foreign legion officer Bob Carter (Ralph Forbes) and his younger brother Don (Ben Alexander) vie for the attentions of sexy cabaret singer Nina (Halla Linda). This rivalry is forgotten when they're both captured and tortured by the Arabs. The one new element of this film is the identity of the brother who gives up the girl and gets killed (it won't be revealed here, but it is quite a switch from the usual cliché). By the way, Ralph Forbes was one of the stars of the 1927 version of Beau Geste, from which Legion of Missing Men steals shamelessly.
