The Desert Song is a 1953 film version in Technicolor of Sigmund Rombergs operetta. It is the third film version of the operetta, the third made by Warner Bros., and the second in full threestrip Technicolor. Although it was released in 1953, it was not made in widescreen at that time TwentiethCentury Fox held the rights to Cinemascope, which was introduced that year in the film The Robe.
The conclusion to the film is slightly different, since El Khobar Gordon MacRae is not Birabeaus son here. After the final battle, the Generals soldiers realize that El Khobar and the Riffs were actually on their side and helped in preventing an uprising. When one asks, And where is El Khobar?, MacRae, as the professor, enters carrying El Khobars clothes, and quietly announces El Khobar is dead. Margot is griefstricken, but Birabeau, suspecting the truth, mischievously says that they can all be grateful to the ghost of El Khobar, winking as he says this. As soon as they are alone, MacRae begins to sing the song One Alone to Margot, making her realize that her boring Latin tutor and the dashing El Khobar are one and the same. She rushes into his arms.One song not by Romberg, Gay Parisienne, written for the 1943 film version of the show, is retained for this film. ........
