With exclusive access to the new technology used in bringing the superhero to the big screen and interviews with the director and stars, Willem Dafoe, Tobey Maguire and Kirsten Dunst. The programme asks if Spider-Man were real how would science make sense of his powers? Meeting scientists in California who have developed fluorescent mice using a new technique which can transfer genes from species to species. Could this explain how Peter Parker got his amazing abilities? Tomorrow's World also travels the globe in the search for the holy grail of material science - artificial spiders' silk.
