It looks like Sienna Miller's extra security was a good idea after all. According to FemaleFirst, Sienna Miller has been on the receiving end of death threats from the very same Muslim fundamentalist groups that had her security people worried in the first place.
Islamic extremists are furious the actress is starring in 'Interview', a remake of director Theo van Gogh's 2003 thriller.
The Dutch director was murdered in 2004 after his controversial film 'Submission' sparked outrage among Islamic fundamentalists.
Sienna, who is currently shooting the film in New York, is being targeted by similar political groups. She has been sent letters warning her "she will be sorry" unless she pulls out of filming.
A crew member told Britain's Daily Star newspaper: "Sienna refuses to give in to these threats. The film hasn't got anything to do with Islam. But because it's being made as a tribute to Theo, the Islamic fundamentalists have hit the roof."
Her co-star, 'Reservoir Dogs' star Steve Buscemi has received similar death threats.
He is also directing the movie and has promised to protect Sienna with the best security in America.
Okay, so that's not really funny, is it? I mean, it's not really nice to make fun of someone who is being terrorized by religious zealots.
Here are some smaller pictures of Sienna Miller on the set of Interview. I'm not sure if she's crying for a scene, or if she just got another phone call.
