Now that The Chronicles of Narnia is a bona fide billion-dollar cinematic franchise, producers are exploring the rest of author C.S. Lewis' bibliography for adaptable works.  Variety reports that Mpower Pictures will team up with Beloved Pictures to bring Lewis' 1945 religious allegory The Great Divorce to the big screen.  The rights have been secured at Beloved for awhile, but fresh off The Stoning of Soraya M., Mpower is new to the project.  Children's book author N.D. Wilson (the 100 Cupboards trilogy) is attached to write the screenplay.

The fantasy novel revolves around a resident of Hell who boards a bus en route to Heaven.  Hit the jump for a full synopsis.

Here's the synopsis for The Great Divorce via Amazon:

What if anyone in Hell could take a bus trip to Heaven and stay there forever if they wanted to?

In The Great Divorce C. S. Lewis again employs his formidable talent for fable and allegory. The writer finds himself in Hell boarding a bus bound for Heaven. The amazing opportunity is that anyone who wants to stay in Heaven, can. This is the starting point for an extraordinary meditation upon good and evil, grace and judgment. Lewis's revolutionary idea is the discovery that the gates of Hell are locked from the inside. In Lewis's own words, "If we insist on keeping Hell (or even earth) we shall not see Heaven: if we accept Heaven we shall not be able to retain even the smallest and most intimate souvenirs of Hell."
