Žižek, as well as similar works. The 1927 film Sunrise: A Song of Two Humans was also influential. Location A Clockwork Orange was one of the inspirations for the futuristic, yet battered patina of 2027 London. Children of Men was the second film Cuarón made in London, with the director portraying the city using single, wide shots. While Cuarón was preparing the film, the London bombings occurred, but the director did not consider moving the production. "It would have been impossible to shoot anywhere but London, because of the very obvious way the locations were incorporated into the film", Cuarón told Variety. "For example, the shot of Fleet Street looking towards St. Paul's would have been impossible to shoot anywhere else." Due to these circumstances, the opening terrorist attack scene on Fleet Street was shot a month and a half after the London bombing. Cuarón chose to shoot some scenes in East London, a location he considered "a place without glamour". The set locations were dressed to make them appear even more run-down; Cuarón says he told the crew "'Let's make it more Mexican'. In other words, we'd look at a location and then say: yes, but in Mexico there would be this and this. It was about making the place look run-down. It was about poverty." He also made use of London's most popular sites, shooting in locations like Trafalgar Square and Battersea Power Station. The power station scene (whose conversion into an art archive is a reference to the Tate Modern), has been compared to Antonioni's Red Desert. Cuarón added a pig balloon to the scene as homage to Pink Floyd's Animals. Other art works visible in this scene include Michelangelo's David, Picasso's Guernica, and Banksy's Kissing Coppers. London visual effects companies Double Negative and Framestore worked directly with Cuarón from script to post production, developing effects and creating "environments and shots that wouldn't otherwise be possible". The Historic Dockyard in Chatham was used to film the scene in the empty activist safehouse. Style and design "In most sci-fi epics, special effects substitute for story. Here they seamlessly advance it", observes Colin Covert of Star Tribune. Billboards were designed to balance a contemporary and futuristic appearance as well as easily visualizing what else was occurring in the rest of the world at the time, and cars were made to resemble modern ones at first glance, although a closer
