Angels & Demons is a bestselling mystery novel by Dan Brown. Published in 2000, it introduces the character Robert Langdon (Tom Hanks), who is also the principal character of Brown’s subsequent, better known novel The Da Vinci Code. It also shares many stylistic elements with the better known novel, such as conspiracies of secret societies, a single-day time frame and the Roman Catholic Church. The story involves a conflict between an ancient group, the Illuminati, and the Roman Catholic Church. Sony recently released a teaser trailer that should whet the appeitite of any Davinci Code fans out there.
Filming was originally to begin in February 2008 for a December 2008 release, but because of the 2007–2008 Writers Guild of America strike, production was pushed back for a May 15, 2009 release. Along with Tom Hanks, the Da Vinci Code director Ron Howard and screenwriter Akiva Goldsman also return. Ewan McGregor plays the Camerlengo Carlo Ventresca.
