Following is a 1998 British neo-noir film written and directed by Christopher Nolan. It tells the story of a young man who follows strangers around the streets of London and is drawn into a criminal underworld when he fails to keep his distance.

His debut film, it was designed to be as inexpensive as possible to make: scenes were heavily rehearsed so that just one or two takes were needed, thus economising on 16 mm film stock, the production's greatest expense, and for which Nolan was paying from his salary. Without expensive professional lighting equipment, Nolan mostly used available light. Apart from providing the script and direction, Nolan also did the photography, editing and production himself. The film has an unusual, non-linear plot structure which has been a feature in several of Nolan's films.

A struggling, unemployed young writer (credited as "The Young Man") takes to following strangers around the streets of London, ostensibly to find inspiration for his first novel. Initially, he sets strict rules for himself regarding whom he should follow and for how long, but soon discards them as he focuses on a well-groomed, handsome man in a dark suit. The man in the suit, having noticed he is being followed, quickly confronts the Young Man and introduces himself as "Cobb". Cobb reveals that he is a serial burglar and invites The Young Man to accompany him on various burglaries. The material gains from these crimes seem to be of secondary importance to Cobb, who takes pleasure in rifling through the personal items in his targets' flats, and doing things such as drinking their wine. He explains that his true passion is using the shock of robbery and violation of property to make his victims re-examine their lives. He sums up his attitude thus: "You take it away, and show them what they had."
