The poster looks like a combination of The Lion King and the kids in the tree part of Jurassic Park.
The Thornberrys are about to embark on a brand new adventure in Africa - and on the big screen! While her parents are shooting a documentary in the Serengeti Plains, Eliza sets out on a mission to rescue a missing cheetah cub from poachers and soon discovers there's more at stake than one wild cat. On a journey that takes her across two continents, Eliza's determined to do whatever it takes to save the animals of the plains - which might mean losing her power to talk to them. Will Eliza give up her gift of gab?
