Despite his roots as the independent filmmaker behind low-budget classics likeFollowingandMemento,Christopher Nolanhas become one of the most prominent blockbuster filmmakers of his generation, and perhaps the truest successor toSteven Spielberg. Nolan often demands extensive budgets for his films, which generally require extensive worldbuilding and intricate designs as a result.

However, Nolan is often considered to be an old-fashioned storyteller due to his determination to use as little computer-generated imagery as possible. Notably, his Best Picture winning World War II epicOppenheimercontained no CGI shots at all. While a science fiction epic likeInterstellarrequired some digital imagery due to its imaginative outer space sequences, that didn’t mean that Nolan gave up his penchant for authenticity all together. In order to ensure that the story was grounded in a recognizable version of Earth,Nolan used over one hundred acres of corn forInterstellar.

Interstellar

When Earth becomes uninhabitable in the future, a farmer and ex-NASA pilot, Joseph Cooper, is tasked to pilot a spacecraft, along with a team of researchers, to find a new planet for humans.

Why Did Nolan Need Real Corn for ‘Interstellar'?

Set in 2067,Interstellarimagines a future where humanity’s resources have been depleted, leaving the world to reject many of the technological advancements that have been made in recent years. Humanity has ironically had to turn back to farming as the primary source of its survival, as the negative environmental effects of overusing unsustainable resources have resulted in a global food shortage. Although the film is a grand science fiction space opera, Nolan incorporates a pro-environmentalist message within theinciting incident inInterstellar.It’s due to the significant damage that the Earth’s naturalistic environments have sustained that NASA has begun searching the universe for other planets that humanity could potentially relocate to.

After determining that there are three potential planets that could sustain human life that are reachable using a black hole, the NASA scientist Professor John Brand (Michael Caine) recruits the widower pilot Cooper Murphy (Matthew McConaughey) to take part in an ambitious outer space mission. Despite his work with the space program in the past, Cooper now works as a farmer, and takes care of his father-in-law, Donald (John Lithgow), and his two children, Tom (TimothéeChalamet) and Murph (Mackenzie Foy).Cooper’s work as a corn farmer represents his humble origins, as he embodies the unspoken heroism within America’s heartland. It’s only after tracking a gravitational anomaly with Murph that Cooper drives through the cornfields and meets up with his cohorts in NASA. It’s due to Cooper’s relatable qualities that he becomes such an inspirational hero thattakesInterstellarinto such unexpectedly emotional places.

Interstellaris certainly not lacking in Nolan’s signature spectacle, as it took home the Academy Award for Best Visual Effects. Although some of the outer space environments and ships required extensive digital imagery in order to develop the futuristic designs,the corn inInterstellarwas grown for real. While Nolan insisted on having real farming fields in the film, he was initially unsure about the time commitment required to grow so much corn. However, Nolan found that several acres had already been grown by hiscollaboratorZack Snyderfor the Kent family farm seen inMan of Steel. Nolan explained in the aforementionedHollywood Reporterarticle:

“Luckily, [director]Zack[Snyder] had grown a bunch of corn, so I said, ‘How much can you really grow practically?’ ” Nolan recalls. “And they had done a couple hundred acres [forMan of Steel], so we looked into it; we found that where we wanted to build our farmhouse really close to the mountains [outside] Calgary. In the end, we got a pretty good crop, and we actually made money on this.”

Corn Is More Important Than You Think in ‘Interstellar’

While Nolan’s insistence on growing “real corn” instead of using CGI farming fields may seem like a strange point for him to focus on,the use of real crops was integral to the thematic implications ofInterstellar. The film is among Nolan’s most emotional projects because the audience must compare the grandiose version of space within Cooper’s outer space adventure with the rather plain and ordinary nature of his life at home with Murph. While he’s tasked with mapping out a future home for the entirety of humanity, Cooper is also forced to make a personal sacrifice that denies him the chance to have a normal life. The blissful shots of his family’s cornfields, accompanied bythe bombastic score byHans Zimmer, show how difficult this decision was for him.

No Director Has Weirder Rules on Set Than Christopher Nolan

The Oscar-winning director of ‘Oppenheimer’ has a lot of intense rules, but they seem to pay off.

Corn actually factors into the narrative progression ofInterstellar. As the film cuts to an older Murph (Jessica Chastain) who is working with her associate Getty (Topher Grace) to identify her father’s location, she finds that her family’s farm has been infected by a plague. to convince Tom (Casey Affleck) and his family to relocate, Murph is forced to burn down the cornfield, resulting in one ofthe film’s most haunting moments. Thematically, this shows that Murph is in some ways rejecting the comforts of her past, and understands that humanity needs to look towards the future if it has any hope of survival.

Nolan Has a Unique Partnership With Zack Snyder

Although Snyder may have lent Nolan a hand by letting him retrofit the cornfields forMan of SteelinInterstellar, it’s not the first time that the two filmmakers have worked together.Man of Steelwas first developeddue to creative frustrations writingThe Dark Knight Rises, which led Nolan and his longtime producing partner (and wife)Emma Thomasto join the Superman reboot as executive producers. Nolan was essential in hiring Snyder to direct the film, and remained as a producer on bothBatman v. Superman: Dawn of JusticeandJustice League.

Nolan has praised Snyder’s work, stating that his controversial 2009 adaptation ofAlan Moore’sbeloved graphic novelWatchmen“was ahead of its time, and that “it would have been fascinating to see it released post-Avengers.” While their films seem to earn completely opposite reviews,Nolan and Snyder are both uncompromisingly stylistic filmmakers who strive for big budget maximalism.Hopefully, Snyder will take a page from Nolan’s book and tell a scaled-back, more focused story again.
