When they announced the Oscar nominations for best animated feature, the one you didn’t recognize was The Secret of Kells, a microbudget Irish feature that somehow was catapulted into the front line with Up, Coraline, Fantastic Mr. Fox, and The Princess and the Frog. You can find some of the details of this Cinderella story here; you can see the movie’s Chicago premiere on Thursday as part of the closing-night program for the European Union Film Festival. Our sidebar for the festival includes a review of this film and five others; The Secret of Kells opens for a full week’s run at Film Center on Friday, April 2.
