This time around Abbott and Costello are wrestling promoters Bud Jones and Lou Hotchkiss. Their star, Abdullah (Wee Willlie Davis), refuses to loose when they tell him to and he returns home to Algeria. The boys have to go after Abdullah and bring him back because they borrowed $5,000 from the syndicate to bring him to America in the first place. However, Abdullah's cousing, Sheik Hamud El Khalid (Douglas Dumbrille) and the evil Foreign Legionnaire Sgt. Axmann (Walter Slezak), have been raiding the railroad being constructed so they can get rich extorting money for protection. The bad guys assume Bud and Lou are spies for the railroad and order them killed. Lou has also upset the Sheik by outbidding him on six beautiful slave girls, including Nicole (Patricia Medina), a French spy. Anyhow, the boys end up enlisting in the Foreing Legion, narrowly avert death several times, and end up saving the day with ample help from Abdullah and Nicole.
This 1950 film, directed by Charles Lamont, was the 25th film featuring Abbott & Costello, then in their 15th year as a comedy team. The film suffers somewhat in comparison to Laurel & Hardy's 1939 classic "The Flying Deuces," but there are enough laughs in this one to make "Abbott and Costello in the Foreign Legion" at least an average comedy by the boys. Of course, to be fair, Costello had faced a pair of serious illnesses, rheumatic fever and a gangrenous gall bladder, in the months before this film was produced. The wrestling sequence remains the comic highlight of the film, along with the mirages the boys encounter in the desert. The bit between Lou and the Commandant where the word play of "we"/"oui" is merely cute. Still, this movie is arguably the second best Foreign Legion comedy of all time, for what that is worth.
