From Empire Online:
Barbarella is a 1968 science fiction film directed by Roger Vadim, based on the French comic series of the same name by Jean-Claude Forest. The film stars Jane Fonda as the title character, a space-traveller and representative of the United Earth government sent to find scientist Durand Durand, who has created a weapon that could destroy humanity. The supporting cast includes John Phillip Law, Anita Pallenberg, Milo O’Shea, Marcel Marceau, David Hemmings, Ugo Tognazzi and Claude Dauphin.

Having expressed an interest in comics and science fiction, Vadim was hired to direct Barbarella after producer Dino De Laurentiis purchased the film rights to the comic series. Vadim attempted to cast several actresses—Brigitte Bardot and Sophia Loren—in the title role before choosing Fonda, his then-wife. A friend of Vadim’s, Terry Southern, wrote the initial screenplay, which changed considerably during filming and led to seven other writers credited in the final release, including Vadim and Forest, the latter of whom also worked on the film’s production design. The film began shooting immediately following the completion of another De Laurentiis comic adaptation, Danger: Diabolik, with both films sharing several cast and crew members.

The film was particularly popular in the United Kingdom, where it was the year’s second-highest-grossing film. Contemporary film critics praised Barbarella’s visuals and cinematography, but found its storyline weak after the first few scenes. Although several attempts at sequels, remakes, and other adaptations have been planned, none of these have entered production.
