Questions abound about the anti-Islam film that's being blamed for provoking Muslims to anger and violence in the Middle East.

A 14-minute trailer of the movie "Innocence of Muslims" was posted recently on YouTube.

The online media sites "BuzzFeed" and "Gawker" are skeptical about the trailer, claiming nearly all the names of characters, including the Islamic prophet Muhammad's, appear to be overdubbed or added after the movie was shot.

One of the actresses in the movie is speaking out, saying the original script was so different from the trailer, that none of the cast suspected what the movie was about.

The woman's identity is being withheld for her family's safety. She said she's more angry at being misled than afraid.

"There was never any mention of Muhammad or Muslims or anything like that," she said. "In the film, I was just playing the role of a mother. I have the actual script. I have the title of the film which was 'Desert Warriors.'"

"We were supposed to be playing a film of how life was 2,000 years ago ... compared to today," the actress continued. "That's what the film was supposed to be about."

The mystery man behind the film has yet to reveal himself.

An anti-Muslim activist claiming to be in touch with the movie producer said he's "terrified they'll kill him if they find him."

Media watchers say the final product is either a very bad re-edit of the original script, or an outright hoax.
