The Desert Song is a 1929 American pre-Code sound (All-Talking) operetta film directed by Roy Del Ruth and starring John Boles, Carlotta King, Louise Fazenda, and Myrna Loy.
The original 1929 version was a pre-Code production which contained content such as sexual innuendo, lewd suggestive humor, and open discussion of themes such as homosexuality (e.g. Johnny Arthur plays a character who is obviously gay).
Film critic Violet LeVoit observes on TCM.com: If Warner Brothers had not sat on the completed reels of this two-strip Technicolor musical for five inexplicable months, it would have beat MGM's Broadway Melody (1929) into theaters and enjoyed the distinction of being the first all-talkie (all-singie?)
But while the considerably stiff and stodgy Broadway Melody won Best Picture in 1929, modern audiences find more to love in this Moroccan desert operetta... not only because of the Oscar Hammerstein lyrics but the snappy direction of Roy Del Ruth, the shadowy, sensuous cinematography by Barney McGill, and how stars John Boles and Carlotta King can (belt) out the bold music with more power than other wispy singers in the early days of amplified sound.
The film elements from this 16mm source are missing a small portion of one of the musical numbers but the complete soundtrack survives intact on Vitaphone disks.
