Sony Studio said Friday that it is postponing production on the Tom Hank's Angels and Demons, which is a prequel to last year's megahit The Da Vinci Code. According to Variety, the script, which was written by Da Vinci screenwriter Akiva Goldsman, was rushed to meet the WGA's Nov. 1 deadline for reaching a new contract with producers, and came in with insurmountable problems. Furthermore, no cast had signed on beyond Hanks.

The Vatican-set thriller was scheduled to begin shooting in February, with Ron Howard at the direct.

The studio had set a Christmas 2008 release date and is now shooting for May 15, 2009.

"While the filmmakers and the studio feel the screenplay is very strong, we do not believe it is the fully realized production draft required of this ambitious project," a Sony spokesperson said.

Angels & Demons was released May 15th, 2009 and stars Tom Hanks, Ewan McGregor, Ayelet Zurer, Stellan Skarsgård, Pierfrancesco Favino, Nikolaj Lie Kaas, Armin Mueller-Stahl, Thure Lindhardt. The film is directed by Ron Howard.
