Cinematical has just received this exclusive teaser poster for City of Ember (click to enlarge), due out this October 10th courtesy of 20th Century Fox and Walden Media. Based on the best-selling novel from Jeanne Duprau, City of Ember was written by Caroline Thompson (Edward Scissorhands) and directed by the very talented Gil Kenan (Monster House). Oh, but the talent doesn't stop there -- check out this cast: Bill Murray, Saoirse Ronan, Tim Robbins, Martin Landau, Toby Jones and Harry Treadaway. And did I mention it was produced by Tom Hanks?

And here's a synopsis for ya: "For generations, the people of the City of Ember have flourished in an amazing world of glittering lights - underground. But Ember's once powerful generator is failing . . . and the great lamps that illuminate the city are starting to flicker. Now, two teenagers in a race against time, must search Ember for clues that will unlock the ancient mystery of the city's existence, and help the citizens escape before the lights go out forever."

Early buzz tells us the film looks gorgeous, so that's definitely a good sign. We've also been told that the first trailer for City of Ember will debut in front of Prince Caspian this weekend. (Chalk up another reason to hang with those peeps over in Narnia.) Once again, City of Ember arrives in theaters on October 10th.

So who's excited for this one?
