28 weeks after the dramatic changes in the film.

In the Three Mills Studio in East London, 28 weeks later, filming began in August 2006 for 65,438+00 weeks. Because we have to rehearse for one week before the official shooting, the shooting time left for juan carlos fresnadillo is actually only nine weeks. Almost all of this film was shot in London. According to the description in the script, the first isolation belt was placed on "Dog Island". In order to shoot this part, the crew got permission to shoot at Canary Wharf in the easternmost part of London, and all the films shot here were filled into some scenes related to "Dog Island" in the film. Producer andrew macdonald said: "Because Canary Wharf is also surrounded by water, it is easy to imagine it as a strategic fortress guarded by the army." The following is a response to the ending of the original book: Doyle, Scarlett, Tammy and Andy escaped from the first quarantine area, and their next step was to cross London, which has become an empty city ... All the scenes related to the City of London were shot at the least crowded time in the morning with the help of the local legislature and the police, and the locations received in the camera also included Tower Bridge, Trafalgar Square, shaftesbury Avenue, Regent's Park and Millennium Bridge.

For director Juan Carlos Fresnadiro, the biggest challenge in the filming process is how to find a real breakthrough for these visually shocking images: "I imagine myself as an audience who might walk into a cinema. I know what kind of movie I want to see, and it's best to smell the familiar characters, as if this story will happen to me at any time ... so I chose a horror documentary. You need a lot of cameras to create a sense of picture taken by a portable camera, which is also related to the performance of actors and the scenery of artists. If any part is not well connected, there will be irreparable mistakes. I know this shooting style is a bit unusual, but it is the best way for you to really face this story. "

Jeremy Renner, one of the actors who participated in the filming, said that it felt like shooting an independent film: "Usually, you get a shooting list, which lists what you should shoot now and when to shoot the next scene ... but here, it's useless, because our director is the kind of pioneer who likes to improvise with a camera. Of course, they will shoot some parts of the film as usual, but the rest depends entirely on the camera-I'm not even sure whether the camera is aimed at my face or my ass. Because of the portable style, the picture is a little shaky, and I feel that the camera runs with you and then travels across London. "
