Epic is a 2013 American animated fantasy action-adventure film loosely based on William Joyce's 1996 children's book The Leaf Men and the Brave Good Bugs. Produced by Blue Sky Studios in association with 20th Century Fox Animation, it was directed by Chris Wedge from a screenplay written by Joyce, James V. Hart, Daniel Shere, and the writing team of Tom J. Astle and Matt Ember, based on a story conceived by Joyce, Hart, and Wedge. It stars the voices of Colin Farrell, Josh Hutcherson, Amanda Seyfried, Christoph Waltz, Aziz Ansari, Chris O'Dowd, Pitbull, Jason Sudeikis, Steven Tyler, and Beyoncé Knowles. In the film, after teenager Mary Katherine gets shrunk and teleported to a tiny woodland kingdom inhabited by talking slugs, flower people and tiny soldiers called Leafmen, she is swept up in a wild adventure between good and evil and, alongside her new friends, must fight to protect the world she never knew existed.
