In May 2006, following the release of the 2006 film adaptation of "The Da Vinci Code", Sony Pictures hired screenwriter Akiva Goldsman, who wrote the film adaptation of "The Da Vinci Code", to adapt "Angels & Demons". 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
The Tibet Code collaborators", which he denied). The series, initially titled "The Last Temple", was rebranded by the publisher as "The Tibet Code", in a nod to the bestselling novel "The Da Vinci Code". In April 2013, DreamWorks Animation announced an adaption of "The Tibet Code" as the first project of its newly formed Chinese venture, Oriental DreamWorks, in collaboration with China Film Group. DreamWorks Animation CEO Jeffrey Katzenberg described the film as "be[ing] for China, like the Indiana Jones and The Da Vinci Code films" and having "all the makings of a world-class, quality, blockbuster franchise."
