Filming was originally to begin in February 2008 and was originally going to be released on December 19, 2008, but because of the 2007–2008 Writers Guild of America strike, the film was pushed back for May 15, 2009. David Koepp rewrote the script before shooting began. Director Ron Howard chose to treat "Angels & Demons" as a sequel to

On April 17, 2006, Google launched its own "Da Vinci Code"-related quest, based around the release of "The Da Vinci Code's" film version.
