George Lucas banned Carrie Fisher from wearing a bra while shooting her role in the Star Wars films.
The actress found fame playing Princess Leia in the phenomenally successful movie series, which gained her legions of loyal fans.
Fisher now reveals she was ordered to ditch her bra on set to ensure the shoot stayed true to life.
She tells the New York Daily News, "Whatever I would have put on (underneath the costume) would have shown through. It was very fine material.
"I asked George to explain it to me and he said, 'When you go into space, you're weightless and then your body expands. But your bra doesn't.' So he told me you'd get strangled by your bra."
