Sharmeen Obaid-Chinoy made history earlier this year when she won Pakistan's first Oscar, feted across the country for exposing the horrors endured by women whose faces are obliterated in devastating acid attacks.
Her 40-minute film focuses on Zakia and Rukhsana as they fight to rebuild their lives after being attacked by their husbands, and British Pakistani plastic surgeon Mohammad Jawad who tries to help repair their shattered looks.
When "Saving Face" scooped a coveted gold statuette in the documentary category in Hollywood in February, campaigners were initially jubilant.
The Acid Survivors Foundation Pakistan (ASF) had cooperated on the film but some survivors now fear a backlash in a deeply conservative society -- and are taking legal action against the producers.
"We had no idea it would be a hit and win an Oscar. It's completely wrong. We never allowed them to show this film in Pakistan," said Naila Farhat, 22, who features fleetingly in the documentary.
