The actress, who made her big screen debut in 1960s Tall Story, left nothing to the imagination when she stripped off for Barbarella.
In a shot from behind-the-scenes of the movie – which turns 60 next year – the two-time Academy Award winner bravely got topless.
Wearing her blonde tresses down in a voluminous ‘do, Jane was seen in little more than a furry blanket and futuristic accessories.
The sci-fi offering saw the film legend take on the title role: a 41st-century representative of the United Earth government, who is sent to find scientist Durand Durand (played by Milo O’Shea).
In a snap from three years earlier, Jane’s legs took centre-stage as she modelled a tiny lace basque.
With her hair in a up ‘do, the mother-of-three teamed the striped corset, complete with bow detailing, with tights and heels.
Jane’s incredible figure was impossible to miss in the image, taken in the same year as she wowed in Cat Ballou.
A third snapchat from her hey day pictured her back in 1962 and saw her flash serious cleavage in a low-cut top.
Flashing a seductive gaze at the camera, Jane teamed her ruched blouse with a pendant necklace and lashings of mascara.
The beauty, who has since been married three times: Ted Turner (1991–2001), Tom Hayden (1973–1990) and Roger Vadim (1965–1973), went on to win Best Actress Oscars for Klute and Coming Home.
