“Sleepless Knights” was an idea Morrison scripted that would be a sort of fairy tale, which del Toro was attached to direct. Thanks to a time-machine error, the world gets stuck on Halloween, permanently -- kind of like “Groundhog Day,” but for everyone. Ghosts, goblins, and other creatures think of it as a free-for-all, and start running wild. That is, until a new kind of Ghostbusters, called the "Sleepless Knights," start fighting them.

Though the premise could work as a creep-out horror movie, Morrison thought it of it as a family-friendly, coming-of-age, fantasy-adventure film, and wrote the lead role as a 15-year-old teenager named Alex Bradbury (a nod to Ray Bradbury).

The idea was sold to Dreamworks exec Michael DeLuca, and producer Don Murphy came aboard. And then nothing. Morrison continued plugging away on a second draft, and still nothing. At Comic-Con, he said the project was “resurrected” (apt for a story about the dead). But now, he’s not so sure.

“That was the last we heard, but now it seems to be doing something else,” Morrison told us. “So it’s no longer, as far as I know. It’s not at Dreamworks anymore, as far as I know. We spoke to some people after the convention, and that aspect seems to have gone quiet again.”

No matter -- both Morrison and del Toro have plenty of projects to keep them both busy, what with Morrison’s “Area 51” film and the adaptation of “We3,” and del Toro’s work on "The Hobbit." But if the script is in, perhaps it just needs another director to have time to take it on.

Would you want to see Morrison's "Sleepless Knights"? Who do you think would be good to direct it?
