The Secret of Kells official U.S. release trailer.
This film has been released in Ireland and in Europe, and has played a limited Oscar-qualifying run in a few theaters in the U.S., but has not yet been widely released . But it looks like it is on track now to get a proper theatrical release in the United States.
(the Oscar nomination for "Best Animated Feature Film" helped, I think !)
I'm hoping to see this and Sylvain Chomet's (Triplets of Belleville) new feature film "The Illusionist" soon.
