What was Christopher Nolan's debut feature film released in 1998?

Christopher Nolan's debut feature film released in 1998 was Following. The British neo-noir thriller introduced the director's interest in fractured timelines, unreliable perspectives, and characters drawn into criminal worlds.

Nolan wrote, directed, photographed, produced, and edited the film himself. It was made on an extremely small budget—about $6,000—and was filmed mainly on weekends over roughly a year while Nolan and his collaborators worked around their day jobs. Many cast and crew members were friends or colleagues.

The story follows an unemployed young writer who trails strangers through London for material. His experiment changes when one of the people he follows, a burglar, notices him and begins drawing him into a dangerous underworld. The film's non-linear structure foreshadows Nolan's later work.

A common mix-up is Memento, released in 2000. Memento was Nolan's breakthrough feature, but Following was his first feature-length directorial effort. Doodlebug, released in 1997, was a short film rather than his debut feature.
