Unholy Night by Seth Grahame-Greene's still in development at Warner Brothers

But will there be werewolves, that's what I want to know! Seth Grahame-Smith, the author who gave us Pride and Prejudice and Zombies and Abraham Lincoln:Vampire Hunter has another book, Unholy Night, hitting the shelves in the spring. And Warner Bros has already agreed to pay Grahame-Smith a cool two million for the screen rights. Oh, I how I wish that it were me!
To be fair, it isn't all as easy as taking candy from a baby. Grahame-Smith does actually have to write the screenplay for the movie which he and his partner David Katzenberg (KatzSmith) will produce along with David Heyman and Jeffrey Clifford of Heydey Films.

UPDATED 11/11/2017 Unholy Night is still listed as being In Development

Grahame-Smith (the very British name is a nom de plume by the way, his real name is Seth Jared Green and he hails from good ol' NYC) also penned Dark Shadows, the Tim Burton film based on the wildly popular television show from the 60's. I remember racing home from high school in the late 60's, arriving breathless and desperate to see every bleeding second!  He also wrote the screenlay for his own Abraham Lincoln:Vampire Hunter coming out early in 2012. Tim Burton produced with Timur Bekmambatov directing.

Grahame-Smith (what a pretentious name to actually pick out for yourself!) has had a wild and woolly path to the good life. Check out his website at sethgrahamesmith.com and take a gander at his other books. Whaaaat?!
The Big Book of Porn: A Penetrating Look at the World of Dirty Movies, The Spider-Man Handbook: The Ultimate Training Manual, and How to Survive A Horror Movie.

Here's Amazon's summary of  Unholy Night. It sounds like revisionist history - the stuff Seth seems to love - but not a vampire, zombie or werewolf in the lot. Again I say -Whaaat?!

‘‘They're an iconic part of history's most celebrated birth. But what do we really know about the Three Kings of the Nativity, besides the fact that they followed a star to Bethlehem bearing strange gifts? The Bible has little to say about this enigmatic trio. But leave it to Seth Grahame-Smith, the brilliant and twisted mind behind Abraham Lincoln: Vampire Hunter and Pride and Prejudice and Zombies to take a little mystery, bend a little history, and weave an epic tale.

In Grahame-Smith's telling, the so-called "Three Wise Men" are infamous thieves, led by the dark, murderous Balthazar. After a daring escape from Herod's prison, they stumble upon the famous manger and its newborn king. The last thing Balthazar needs is to be slowed down by young Joseph, Mary and their infant. But when Herod's men begin to slaughter the first born in Judea, he has no choice but to help them escape to Egypt.

It's the beginning of an adventure that will see them fight the last magical creatures of the Old Testament; cross paths with biblical figures like Pontius Pilate and John the Baptist; and finally deliver them to Egypt. It may just be the greatest story never told.
