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.
