Land of Giants: A Walking With Dinosaurs Special

A closer look at the science of Human evolution, and how much early humans might've contributed to the extinction of large mammals during the Ice Age.

Combining fact and informed speculation with cutting-edge computer graphics and animatronics effects, the series set out to create the most accurate portrayal of prehistoric animals ever seen on the screen.

In a search for clues about size, the documentary shows why the sun and planets are so large, why insects have shrunk in the course of evolution and how tall trees can actually grow. Fantastic thought experiments are visualized: animals grow many times their normal size and a man is shrunk to the size of an insect. The results of the unnatural reversal of size ratios have incredible consequences. What are the advantages and disadvantages? "Size matters" is a scientific documentary narrated with fictional scenes. Parallel worlds are created in which size appears in a completely new light, often in a different way than previously known. Modern, astonishing CGI sequences support internationally recognized scientists on a journey to both ends of the size scale and help to understand the world in its dimensions.

Walking With Prehistoric Beasts explores how life on earth first began. Using real footage, the series goes inside the body of our monster ancestors. For the first time, morphing technology is used to reveal how our ancestors evolved.

Zoologist Nigel Marvin travels back in time to visit deadly creatures of the prehistoric oceans.

A behind-the-scenes look at how the animators, sculptors and palaeontologists, using the latest state-of-the-art animatronics and computer graphics, collaborated to re-create not just these pre-historic behemoths but their behaviour as well for the BBC natural history documentary miniseries Walking with Dinosaurs.

A Walking with Dinosaurs Special - broadcast in North America as Chased by Dinosaurs - is a two-part British documentary film series featuring Nigel Marven and his "team of fellow explorers" as time-travellers who encounter dinosaurs in the wild. Most of the creatures were not featured in the original Walking with Dinosaurs series.

A look at the unusual process used in the making of the film Shortbus (2006) featuring interviews, behind the scenes footage and clips from the feature film. Director John Cameron Mitchell starts with the concept of using real sex in a film with a positive message. The cast of unknowns is selected from homemade audition tapes and then a callback audition workshop. More acting workshops are used to develop the characters and script. The project overcomes a number of obstacles and the rest of the film's development is followed up until its premiere at the Cannes Film Festival.

Set 70 million years ago in the Cretaceous period in North America, this animated docu/drama follows the journey of a young Edmontosaurus named Scar and his herd as they migrate south for the winter. This film depicts recent findings about Dinosaurs, such as Tyrannosaurs with feathers.
