That would be James McTeigue's The Raven; the director began discussing his film during press for last summer's Ninja Assassin. At the time, he told Cinematical that it "is about the fictionalized last five days of Edgar Allan Poe. There's a serial killer loose in 1850s Baltimore who's killing people in the manner Poe kills people in his stories. And it's a race against time for Poe and a detective to find the killer. I'm in the middle of casting at the moment, I was scouting in Europe and just got back." Ben Livingston and Hannah Shakespeare (Loverboy) penned the screenplay.
It was previously reported that Jeremy Renner and Ewan McGregor would star in the movie -- perhaps with McGregor as the killer? -- but for now, it's anyone's guess who will be opposite Cusack. Of course, I'm assuming that he'll be playing Poe, but perhaps he'll be the killer? In any case, it will be great to see Cusack on the big screen again. Now if you'll excuse me, I have to go rewatch Hot Tub Time Machine again.
[Thanks to the kind commenters who pointed out the misspelling of Allan.]
