Production of the film was announced on June 23, 1949, after producer
Sol Lesser signed a new distribution agreement for his "Tarzan" pictures with
RKO Pictures. The working title of the film had been
Tarzan and the Golden Lion. But the June 23 announcement changed it to
Tarzan and the Slave Girl and also named Lex Barker as the star. Vanessa Brown was signed to play Jane two weeks later. Hans Jacoby, who had scripted the highly popular
Tarzan and the Amazons, turned in the screenplay for the film. Some location shooting was done in
Baldwin Park, California, the
Los Angeles County Arboretum and Botanic Garden, and the
Iverson Movie Ranch. But most of the filming was done on the
RKO Forty Acres backlot. Sholem brought
Marilyn Monroe out to see Lesser, Sholem brought Monroe to see Lesser eight times in all, but in the end Lesser settled on Vanessa Brown. Signed by
20th Century Fox, she'd been loaned out to RKO several times. The slave girl in the title is Lola, played by Denise Darcel. Although previous films had made it clear that Tarzan and Jane were husband and wife, this film depicted Jane as Tarzan's girlfriend—which allowed Lola to compete for Tarzan's affections without implying that she was an adulterer. while
Eva Gabor also has a non-speaking background role as a slave girls. Suffering from
Parkinson's disease and having already had several heart attacks, Tarzan creator
Edgar Rice Burroughs visited the set during production. It was one of his last public appearances, according to Burrough's daughter, Joan. Burroughs died on March 19, 1950, just four days after the film's release. ==Critical reception==
