City of Ember movie

Never heard of the movie City of Ember before I saw it while flipping channels and stopped to give it a chance. Turns out it stars Seauoioaercioe (or however it's spelled) (I forget her last name too) and some other people. She's the same one who starred in that girl-assassin movie everyone was talking about several months ago, except this movie was made way back when she was much younger and presumably more interesting to many of us. I wouldn't call it a great movie, but it didn't suck, and she was pretty good in it, so if you see it around, take a look.
