When you're as small as an ant, the world is big - and adventure is bigger! That's what young Lucas discovers after he aims his water pistil at some hapless ants. They retaliate with a secret potion that shrinks "the Destroyer" to their size... and turns an anthill into a mountain of thrills, action and laughs! Julia Roberts, Nicholas Cage, Merly Streep and Paul Giamatti head the voice cast of this rollicking, warm-hearted family treat.
