dystopian future ravaged by blight, but populated with hardy folk who refuse to bow to despair." His brother Christopher had worked on other science fiction scripts but decided to take the Interstellar script and choose among the vast array of ideas presented by Jonathan and Thorne, picking what he felt, as director, he could get "across to the audience and hopefully not lose them," before he merged it with a script he had worked on for years on his own. Christopher kept in place Jonathan's conception of the first hour, which is set on a resource depleted Earth in the near future. The setting was inspired by the Dust Bowl that took place in the United States during the Great Depression in the 1930s. He revised the rest of the script, where a team travels into space, instead.

Cinematographer Hoyte van Hoytema was hired for Interstellar, as Wally Pfister, Nolan's cinematographer on all of his previous films, was making his directorial debut working on Transcendence (2014). More IMAX cameras were used for Interstellar than for any of Nolan's previous films. To minimize the use of computer-generated imagery (CGI), the director had practical locations
