Los Angeles (CNN) - Lily Dionne had been in Hollywood a week when she answered an ad on Craigslist looking for actors for an action-adventure film called "Desert Warrior."

Now, Dionne says she feels betrayed by the California filmmaker who turned the low budget-movie with a threadbare plot into an anti-Islam film that provoked outrage - with sometimes violent results - in parts of the Muslim world.

When news broke that violent mobs attacked the U.S. consulate in the Libyan city of Benghazi, leaving Ambassador Chris Stevens and three other Americans dead, she was overwhelmed.

"I was shaking when I found out. I had no idea," Dionne told CNN on Sunday. "This was a movie that I thought no one would ever see."

Dionne knew the filmmaker as Sam Bacile. But federal officials say his name is Nakoula Basseley Nakoula, a convicted felon with a history of using aliases to hide his actions.
