TV's most-watched history series brings to life the compelling stories from our past that inform our understanding of the world today.

From strange abductions, to mutated species, to bizarre occurrences, there are some phenomena that science cannot - or will not - explain. This summer Science Channel unveils some of these shocking and mind-boggling cases from around the world in the world premiere series THE UNEXPLAINED FILES. From mysterious disappearances and UFO encounters, to unidentified fanged predators and reported curses, THE UNEXPLAINED FILES investigates actual, inexplicable occurrences that have confounded scientists and inspired legends. Science Channel invites viewers on a mystifying journey that will challenge disbelief with THE UNEXPLAINED FILES.

In the series, "Wallace will take a light hearted and humorous look at the real-life inventors, contraptions, gadgets and inventions, with the silent help of Gromit. The series aims to inspire a whole new generation of innovative minds by showing them real, but mind-boggling, machines and inventions from around the world that have influenced his illustrious inventing career" (the BBC press statement). Peter Sallis reprised his role as the voice of Wallace. The filmed inserts are mostly narrated by Ashley Jensen, with one in each episode presented in-vision by Jem Stansfield. John Sparkes also voices a portion in the unseen character of archivist Goronwy.

This spectacular five-part series, presented by Tony Robinson, investigates the history of natural disasters, from the planet's beginnings to the present, putting a new perspective on our existence – that we are the product of catastrophe. Using the latest CGI effects and featuring scientific experts, the series reveals how the evolution of life on Earth has been shaped by lethal catastrophes that have caused mass extinctions, almost to the point of wiping out life altogether.
