Screenwriter Jack Thorne (A Long Way Down, How I Live Now) has signed on to write the screenplay for Sandman, based on Neil Gaiman's comic book series.

We first reported on this project in December, when Joseph Gordon-Levitt was finalizing a deal to star, produce and direct this adaptation. The actor clarified last month that he is currently only attached to produce, although the hope is that he will come aboard to star and direct as well.

The story centers on Morpheus, who represents Dreams in a family known as The Endless, who personify several different aspects of life, such as Death, Desire, Despair, Delirium, Destruction and Destiny. After being held captive by a wizard for the past 70 years, Morpheus escapes, going on a quest for revenge, while trying to rebuild his empire and adapt to the current society. The comic book series spanned 75 issues between 1989 and 1996.

Neil Gaiman is serving as executive producer, with Joseph Gordon-Levitt and David S. Goyer producing. No production schedule was given.
