From Deadline.com:

Valiant Entertainment and The Mummy producer Sean Daniel are teaming up to turn the Valiant Comic Shadowman into a live action feature. They've made a deal with J. Michael Straczynski to write the script.

"Shadowman is a character who lives in a unique world that mixes the modern world with that which is most ancient within us," Straczynski. "The New Orleans vibe and history, and the struggle to find a balance with the personality within him, is a perfect dramatic vehicle. We've already finished the outline and there's a lot of action, much of it unique to what Shadowman can do.but at the core of it, there's a strong character, world and mythology that can be explored across multiple subsequent films. This is gonna be fun."
