IMDB doesn't have it listed yet, but Coscarelli seems excited:
The story follows two goofballs who get caught up in a freaky fight against (deep breath...) mutated victims of a strange drug that allows them to drift across time and dimensions and the horrific invasion that may be taking place on Earth because of them. Coscarelli compares JOHN DIES to his previous popular adaptation: “My feelings for JOHN are similar to how they were for Joe R. Lansdale's BUBBA HO-TEP,” he says. “Prior to filming that movie, I’d reread the Lansdale novella and absolutely knew it would make a terrific movie. I feel the same way about JOHN. David Wong is a terrific new talent. He effortlessly blends genres and creates genuine dread. I’m thrilled to be working on a project that’s firmly planted in the genre, yet different and highly original.”AICN has some more info:
"I was greatly impressed by David Wong's crazed originality and impressive imagination," revealed Coscarelli. "He's like a mash-up of Douglass Adams and Stephen King, both smart and goofy, scary and funny -- it really spoke to me. JDatE is as addictive as the 'Soy Sauce' street drug that kicks the plot into gear."I have no idea how long this will take to make it to the screen, but I imagine it would be a while (this is what sucks about keeping track of movies in production - you always find out about the movies years before they're made). In any case, I'm really looking forward to this. Coscarelli is a great director and would be a good match for Wong's style. After all, this is the director who made a movie about an aging Elvis (with a black JFK sidekick) battling a mummy in a Texas old folks home. It's a perfect match.
