English: The Cheese Mites (1903) is a British short silent documentary film, produced by Charles Urban and directed by F. Martin Duncan. Part of Charles Urban's 1903 'Unseen World' series, which brought the microscopic world to the screen, Cheese Mites showed large-as-crabs mites wandering about the nation's favourite lunchtime snack to the joyful disgust of audiences. For 80 years the BFI's archives held only the shot of the creepy crawlies. Now, however, a new version has been discovered, with an opening showing a professor (F Martin Duncan) horrified by examining his bread and cheese through a magnifying glass.
