The film Barbarella is a 1968 science fiction film directed by Roger Vadim based on the French comic Barbarella. The film stars Jane Fonda as Barbarella, a representative of the United Earth government in the 41st century sent out to locate the scientist Durand Durand whose positronic ray could end humanity.
Producer Dino De Laurentiis bought the rights to adapt Barbarella into a film. Vadim took the role as director as he had been a fan of comics and wanted to adapt one to film. Vadim attempted to cast several actors in the title role, including Virna Lisi, Brigitte Bardot and Sophia Loren before casting his then wife, Jane Fonda. Vadim also had his friend Terry Southern write the screenplay; this was heavily altered during filming and several other writers are credited with it.
