Directors Al Giddings and David Clark, whose previous credits include Galapagos: Beyond Darwin, return to the flora and fauna of the Galapagos Islands for this IMAX documentary. The film focuses on the work of Smithsonian-based biologist Carol Baldwin and outlines Charles Darwin's theories on natural selection. Highlights include footage of the giant Galapagos tortoise and the Galapagos iguana, which perfectly camouflages itself against the gray rock on which it suns itself. Kenneth Branagh narrates.~ Jonathan Crow, All Movie Guide
