Johnny Depp and Amber Heard might have been victims of a Peeping Tom who shot upskirt videos during the shooting of several of his movies ... so claim 3 women in a new lawsuit.
Kevin Thomas Roy -- a longtime assistant director with credits on Depp's 'Rum Diary' and "Pirates of the Caribbean: On Stranger Tides" -- is being sued by 3 women for invasion of privacy and emotional distress ... this according to legal docs obtained by TMZ.
The women say Roy was closely associated with Depp's production team and there's a "high probability" Amber was secretly shot. The suit doesn't specifically mention which movie ... but Amber worked with Johnny in 'Rum.'
The suit claims Johnny may have also been a victim, but no specifics are provided.
Roy is accused of using his phone and planting hidden cameras in bathrooms and other private areas to videotape his friends, co-workers and actors. The suit alleges Roy kept videos going back 7 years ... showing people in various states of undress.
And get this ... according to the suit, Roy secretly shot video of his wife's sister's honeymoon.
According to the docs ... Roy's wife discovered the videos and turned it over to cops. He eventually pled no contest to 2 counts of invasion of privacy and was booted from Directors Guild of America.
