Chris Packham embarks on a global journey to discover the truth about the Tyrannosaurus rex, which has endured centuries of scientific inaccuracy and Hollywood misrepresentation. The naturalist uses new studies into dinosaur skin, teeth and muscles, as well as groundbreaking insights into its behaviour to create the most accurate CGI representation of the dinosaur ever produced. To help, Chris speaks to experts in birds, biomechanics and alligators, and has access to one of the most complete Tyrannosaurus rex skeletons in existence.
