Wormwood on Film

Pic, which Walden hopes to release in 2008, is the company’s second Lewis collaboration following “The Chronicles of Narnia: The Lion, the Witch and the Wardrobe,” which grossed $744 million worldwide. The sequel to that pic, “Prince Caspian,” is due out next year.

Like “Narnia,” “The Screwtape Letters” — which is described as a midbudget, primarily live-action pic — embodies Christian themes.

First published in 1942, “The Screwtape Letters” takes the form of a series of missives from a senior demon, Screwtape, to his wannabe diabolical nephew, Wormwood. As a mentor, Screwtape advises his protege on the finer points of undermining faith and promoting sin. His instructions are interspersed with observations on human nature and Christian doctrine.

Since taking over the publishing of “The Screwtape Letters” in 2001, HarperSanFrancisco has sold almost 1 million copies of the trade paperback alone.
