Cindy Lee Garcia said the original "Desert Warriors" script and production were without references to religion, and did not include Prophet Muhammad (PBHU) character.
"It wasn't based on anything to do with religion, it was just on how things were run in Egypt,” Garcia said. “There wasn't anything about (Prophet) Muhammad or Muslims or anything."
She added that she and other actors complained that their lines had been changed.
An unnamed member of the production staff, who worked directly on the film and has a copy of the original script, corroborated the actress's account, adding that it mentions neither Prophet Muhammad nor Islam.
Sarah Abdurrahman, a producer for On the Media, has said words and dialogue about Prophet Muhammad (PBUH) were dubbed into the film's audio track during postproduction.
The film's supposed writer and director, a man calling himself Sam Bacile, has said his two-hour end product, "Innocence of Muslims," was meant to be a provocative political statement in condemnation of Islam.
Outrage is growing across the Muslim world over the USD 5-million movie that was financed by more than 100 Zionists.
The crew and the actors of a movie deemed offensive to Prophet Muhammad (PBUH) say the Israeli-American producer of the film lied about his objectives and unaware it was about Islam’s holiest figure.
"The entire cast and crew are extremely upset and feel taken advantage of by the producer," they said in a statement to CNN on Wednesday.
"We are 100% not behind this film and were grossly misled about its intent and purpose," It added.
"We are shocked by the drastic rewrites of the script and lies that were told to all involved. We are deeply saddened by the tragedies that have occurred," the statement pointed out.
Meanwhile, an actress in the anti-Islam movie says she will sue the filmmaker and that the film's script, originally titled "Desert Warriors," was a "historical Arabian Desert adventure film."
