28 Days Later - Production

Production

28 Days Later features scenes set in normally bustling parts of London such as Westminster Bridge, Piccadilly Circus, Horse Guards Parade, and Oxford Street. In order to depict these locations as desolate, the film crew closed off sections of street for minutes at a time, usually in early morning to minimise disruption. Portions of the film were shot on a Canon XL1 digital video camera. DV cameras are much smaller and more manoeuvrable than traditional film cameras, which would have been impractical on such brief shoots. The scenes of the M1 motorway completely devoid of traffic were also filmed within very limited time periods. A mobile police roadblock slowed traffic sufficiently to leave a long section of carriageway empty while the scene was filmed. The section depicted in the film was actually located at Milton Keynes, nowhere near Manchester. For the London scene where Jim walks by the overturned double-decker bus, the film crew placed the bus on its side and removed it when the shot was finished, all within 20 minutes. Much of the filming took place prior to the September 11 attacks, and in the audio commentary Boyle notes the parallel between the "missing persons" flyers seen at the beginning of the film and similar flyers posted in New York City in the wake of the attacks. Boyle adds that his crew probably would not have been granted permission to close off Whitehall for filming after the terrorist attacks in New York.

The mansion used in the film was Trafalgar Park near Salisbury. Many rooms in the house, including the Cipriani-painted music room and the main hall, were filmed with minimal set decoration. The scenes occurring upstairs were actually filmed downstairs, as the mansion's owner resided upstairs. The old ruins used as the setting for an idyllic interlude in their journey to Manchester were those of Waverley Abbey, Surrey. The end scenes of the film where Jim, Selena and Hannah are living in a rural cottage were filmed around Ennerdale in Cumbria. This reflects the motorway road signage in the film which indicates the trio heading north towards the Lake District National Park.

On the DVD commentary, Boyle and Garland frequently call it a post apocalypse and horror film, commenting on scenes that were specific references to George A. Romero's Dead trilogy. However, during the initial marketing of the film Boyle did try to distance the film from such labels. Boyle identified John Wyndham's The Day of the Triffids as Garland's original inspiration for the story.
