An actress who appears in the anti-Islamic film that has sparked riots in the Muslim world is suing the man believed to have made it.
Cindy Lee Garcia claims she was duped by Nakoula Basseley Nakoula, who is also known as Sam Bacile, and is suing him for fraud and slander.
Under the legal action in Los Angeles, Ms Garcia also wants a judge to make YouTube take down the trailer for the film called Innocence Of Muslims.
Nakoula, who is believed to be a Coptic Christian from Egypt who now lives in the US, has been forced into hiding since the 14-minute trailer rose to prominence last week.
Ms Garcia claimed she was unaware of the film's anti-Muslim content, and said the pages of the script she received had no mention of the Prophet Mohammed, religion or sexual content.
According to her lawsuit, she responded to an ad and thought she was appearing in an ancient Egyptian adventure film called Desert Warriors.
Dialogue in the amateurish film was later dubbed to include anti-Islamic messages and to portray Mohammed as a fraud, a womaniser and a child molester. It was also translated into Arabic.
"The film is vile and reprehensible," said Ms Garcia's lawyer, Cris Armenta.
She said Ms Garcia had received death threats since the film's trailer began drawing attention, and she is no longer able to care for her grandchildren.
"This lawsuit is not an attack on the First Amendment nor on the right of Americans to say what they think, but does request that the offending content be removed from the internet," the complaint states.
YouTube has refused Ms Garcia's requests to remove the film, according to the lawsuit.
She alleges that keeping it online violates her right of publicity, invades her privacy rights and the post-filming dialogue changes cast her in a false light.
"Garcia had a legally protected interest in her privacy and the right to be free from having hateful words put in her mouth or being depicted as a bigot," the lawsuit states.
YouTube said it was reviewing the complaint. The site is owned by search giant Google and has already blocked users in Saudi Arabia, Libya and Egypt from viewing the Innocence Of Muslims trailer.
It has also blocked the video from being viewed in Indonesia and India, because it violates laws in those countries.
A legal firm representing Nakoula declined to comment on the legal action.
