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.

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.

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 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.

Presenter Nigel Marven walks alongside the biggest dinosaurs that ever lived, providing a sense of perspective as he journeys through the Land of Giants.
