The working title of this film was Flame of Tripoli. The film begins with the following written foreword: "This tale was liberally adapted from an old Tripoli legend which reads simply:" The legend is then written in Arabic without translation. As the legend was scored with comedic music, it is highly likely that the characters were nonsensical. The onscreen credits for Michael Fessier and Ernest Pagano read: "Written for the screen and produced by." Throughout the film, Humpy, the "talking" camel, delivers humorous pieces of narration. According to New York Times, Slave Girl was originally shot as a serious melodrama. When they realized that the film was not working, Fessier and Pagano tried to punch up the film at the last minute with some comedic moments. After test screenings, however, Universal executives discovered that they had a $1,600,000 "turkey" on their hands. The picture sat on the shelf for months, then was assigned to executive producer William Dozier. Aware that the only positive reactions test audiences had to the film were to scenes featuring a camel, Dozier inserted a title card, with a picture of the camel on it, which read: "Look, folks, this is a comedy. You're supposed to laugh." When audiences responded to the card, Dozier then ordered the addition of the talking camel narrator.
