This might be something that I should've known about earlier, but I only recently heard that Phil Hester and Mike Huddleston's The Coffin is on Guillermo del Toro's To-Do list. Jess Hickman turned me onto The Coffin at FallCon 2004 and I enjoyed it a lot. Partly because of Hester's complex characters; partly because of Huddleston's dark, moody art. It's about a scientist who finds a way to trap the soul at the moment of death in a containment suit. When the rich guy financing the project kidnaps the scientist's daughter and orders the scientist killed, the scientist traps his own soul and tries to use the containment suit to set things right.
It's still down pretty far on Del Toro's list apparently, so there's not a lot of information about it, except that's it's being conceived as a 3-D film. That should sound cool, but frankly I've always been disappointed in 3-D movies. The gimmick always overshadows the story.
I tend to trust Del Toro though, so we'll see.
