The Cornetto Trilogy: Wells, North London, Letchworth

Shaun of the Dead opens in the Crouch End area of London, where 29-year-old sales advisor Shaun is disrespected by his colleagues. Crouch End is where the film is set, though the crew shot exteriors across North London, including Highgate, Finsbury Park and East Finchley. The film was shot over nine weeks between May and July 2003, on location and at Ealing Studios; the electrical shop where Shaun works is a real shop in North Finchley.

Location precision: The film is set across Crouch End, but exteriors were shot in several North London districts; the pin marks the district centre.

Shaun and Ed plan to wait out the crisis at The Winchester, their favourite pub. Inside, Shaun finds that the Winchester rifle above the bar actually works. The scenes in and around the pub were shot at the Duke of Albany pub in New Cross, South London. The three-storey Victorian building closed and was turned into flats in 2008.

Location precision: The Winchester exists only in the story; it was filmed at a New Cross pub that has since become flats, so no pin is given.

Hot Fuzz was filmed largely in Wells, which became the fictional village of Sandford. Wright wanted St Cuthbert's to be the village centre, so Wells Cathedral was digitally painted out of every shot. At the church fete, journalist Tim Messenger is killed when a cloaked figure dislodges masonry from the tower. A lightning strike in the early 1970s dropped a pinnacle through the nave roof, which may have inspired the scene.

Village florist Leslie Tiller plans to sell her land to the development partners, and she pays for it: a cloaked figure murders her with her own garden shears. The flower shop scene was filmed at Finchley Nurseries in Mill Hill, next to Hendon, while the rest of the village was Wells. Angel suspects the deaths are linked to a recent property deal. Filming lasted eleven weeks from 19 March 2006.

Location precision: The shop is a set in the story; the pin marks the Finchley Nurseries location named by the source in Mill Hill.

In The World's End, Gary King drags his old friends back to Newton Haven to finish the Golden Mile, a pub crawl of 12 pubs. In Letchworth, several premises stood in for those pubs, and the Art Deco Broadway Cinema, built in the 1930s, played the Mermaid. It was also the first cinema outside London to screen the film, with over 800 viewers on opening night.

Location precision: Newton Haven is invented; the pin marks the Letchworth cinema that portrayed the Mermaid pub.

Letchworth Garden City railway station received a makeover to become the Hole in the Wall, another of the film's twelve pubs. Filming took place in Hertfordshire, in Letchworth and Welwyn Garden City, chosen partly because their early twentieth-century architecture evoked British science fiction, especially John Wyndham. In the story, the five friends first tried the crawl as teens in 1990 but never reached the final pub, The World's End.

Location precision: The Hole in the Wall exists only in the film; the pin marks the real station that was dressed as the pub.
