Strike hits Da Vinci Code prequel

A follow-up to The Da Vinci Code has become the first big-screen casualty of the Hollywood writers' strike.

Angels & Demons, a prequel to the movie adaptation of Dan Brown's novel, is being delayed by Columbia Pictures because its script needs more work.

It had been due for release around Christmas 2008, but has now been pencilled in for May 2009.

Writers walked off the job nearly two weeks ago in a row over royalties for their work on DVDs and the internet.

They are due to reopen negotiations with their studios on 26 November.
