In our exclusive clip, slug/snail duo Aziz Ansari and Chris O'Dowd lend insight into the inspiration behind their endlessly quotable Mub and Grub characters. The result is a must-see!

On Blu-ray and DVD August 20, Epic tells the story of an ongoing battle deep in the forest between the forces of good and the forces of evil. When a teenage girl (voiced by Amanda Seyfried) finds herself magically transported/miniaturized into this secret universe, she must band together with a rag-tag team of fun and whimsical characters in order to save their world…and ours.
