Behind the Front is a raucous silent vehicle for Paramount's Mutt-and-Jeff comedy team of Wallace Beery and Raymond Hatton. The film begins during the early months of World War I; myopic detective Beery chases pickpocket Hatton into an "enlistment" party held by pretty socialite Mary Brian. The boys are so moonstruck by her that both agree to sign up for the Army on the spot. The rest of the film is comprised of familiar but hilarious war-comedy sight gags; the overall mood is encapsulated by the wisecracking subtitles of Ralph Spence (sample: "Listening Post...Where Men are Men but wish they weren't"). Behind the Front is punctuated by a terrific closing gag, wherein Beery and Hatton team up after the Armistice to beat to a pulp the young man (Richard Arlen) in charge of the company that produces their indigestible "K Rations"--a young man who happens to be the fiance of leading lady Mary Brian.
