In today’s trailer bin, Atonement‘s Saiorse Ronan must save her own post-apocalyptic Zion in the new teaser for Gil Kenan’s City of Ember, from the children’s book by Jeanne Duprau (which I’m not at all familiar with). I’m not quite sold by this trailer, but an eclectic bunch is coming along for the ride: Bill Murray, Tim Robbins, Harry Treadaway, Martin Landau, Marianne Jean-Baptiste, Toby Jones and Mary Kay Place.
