Robert Rodriguez Barbarella may be dead in the water but as he said "We had all this artwork and screen tests of what it would look like."
The artwork Rodriguez mentions is something he hopes to release at some point so that people can see what he had in mind for his take on the character:
“People said, ‘Why are you doing ‘Barbarella?’… And I showed them the artwork and explained it. They would go, ‘Ooooh, okay!’”
Legendary Italian artist Milo Manara, known for his erotic comics, did some character and costume designs for the movie at some point.
So although none of the screen test have been realsed yet here are the costume designs enjoy!
