Next time you go for a walk in the country, or in the park, or in your garden if you have one, watch out for the teensy-weensie folk dressed like Robin Hood, zipping through the blades of grass, whooshing this way and that on the backs of hummingbirds.
Watch for the talking micro-snails and slugs, too, the jolly caterpillars and sinister Boggans with their pointy teeth and animal cowls, and the beautiful faerie princess-type - you definitely don't want to step on her.
Or, you could just go see Epic, a hyperactive CG cartoon, very loosely adapted from children's book author and artist William Joyce's The Leaf Men and the Brave Good Bugs. Directed by Chris Wedge, of Ice Age fame, and available for viewing in 3-D, if you care for such stuff, Epic is a less-than-seamless mix of action and fantasy in which a feisty teenage human, M.K. (the voice of Amanda Seyfried), paying a visit to her eccentric and heretofore estranged dad (Jason Sudeikis), stumbles into a secret world in the backyard.
