Ever on the lookout for original story ideas, the producers of the "Hopalong Cassidy" series came up with a lulu in Outlaws of the Desert. In this one, Hoppy (William Boyd) and his saddle pals Johnny (Brad King) and California (Andy Clyde), is assigned by the US government to head to Arabia, there to buy a herd of Arabian steeds. Once they've arrived in the desert, our heroes are kidnapped by swarthy Sheik Suleiman (played by future "Cisco Kid" Duncan Renaldo). In his efforts to figure a way out of his predicament, Hoppy must also attempt to rescue distressed damsels Susan Grant (Jean Phillips) and Marie Karitza (Luli Deste). Good escapist fun, Outlaws of the Desert is definitely the most unusual of the early-1940s "Hopalong Cassidy" entries (even though the film's "Arabia" is obviously located near Chatsworth, California). ~ Hal Erickson, All Movie Guide
