Sienna Miller has been given the okay for high security protection on the set of Interview, due to fears she may be the target of Islamic extremists. The film is a remake of the 2003 Theo van Gogh thriller, and a tribute to van Gogh himself - who was murdered in 2004 after his controversial movie Submission incited anger in the Muslim world. The film Interview has no connection to Islam, but there is worry that its association to van Gogh will spark another outcry. "We are very much aware that it requires a high level of security," said a source on the production team. "We will ensure Sienna and her co-star Steve Buscemi are given the sort of protection that this project requires."
