The first trailer for City of Ember has just arrived online (watch it above or over on the film's official site). Cinematical premiered the teaser poster for City of Ember not long ago, and it looks like the folks from 20th Century Fox and Walden Media are itching to get the buzz going on this one by debuting a trailer long before the film's October 10th release date. This will also be the same trailer that plays in front of Prince Caspian this weekend. Based on the best-selling novel, City of Ember was produced by Tom Hanks and stars Bill Murray, Saoirse Ronan, Tim Robbins, Martin Landau, Toby Jones and Harry Treadaway. Directed by Gil Kenan (Monster House), the synopsis for Ember looks like this:

"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."

What say you? I think it definitely has potential, especially with that cast. (Seems like a cool book, too.)
