• Cloud Atlas: (2012) A science fiction film that spans multiple time periods and genres 
• Apollo 13: (1995) A realistic movie about the challenges faced by the crew of NASA’s Apollo 13 mission 

According to Wikipedia, Interstellar was influenced by other science fiction films, including: 

• Metropolis (1927) 
• Blade Runner (1982) 
• Star Wars (1977) 
• Alien (1979)

Christopher Nolan has said that Interstellar was inspired by 2001: A Space Odyssey and Star Wars. 2001: A Space Odyssey is often cited as the greatest sci-fi movie ever made, and has influenced almost every science fiction film made since. Nolan has also said that he helped oversee a new 70mm print of the film, and there are many references to it throughout Interstellar. 

Some other movies that inspired Interstellar include: 

• Contact (1997) 
• Countdown (1967) 
• Marooned (1969) 
• The Right Stuff (1983) 
• Apollo 13 (1995) 
• Space Cowboys (2000) 
• Moon (2009) 

Interstellar also borrows some elements from Inception, particularly its ideas about time and basic story structure.

No, Interstellar is not based on a true story. However, Nolan was inspired by the Dust Bowl of the 1930s, and the interviews at the beginning of the film are real-life accounts from the Ken Burns documentary The Dust Bowl. 

The film’s space habitats were inspired by a theory from physicist Gerard O’Neill. O’Neill came up with a theory for a new-age Noah’s Ark to transport all of humanity to another planet. The spaceship Endurance’s destination is Gargantua, a fictional supermassive black hole. 

While Interstellar may take some liberties with its science, its depiction of wormholes and black holes is still considered one of the more accurate in cinema. However, the extreme time dilation portrayed in the film is not scientifically accurate.

Some say that Interstellar is not 100% accurate, and that its scientific accuracy varies. For example, the planet in the film was designed to be visually stunning, rather than scientifically accurate. Some say that the film’s depiction of a fifth dimension and tesseracts is speculative, and serves more as a plot device. 

However, others say that the film’s depiction of black holes is close to accurate, and that it accurately depicted black holes five years before the first real proof of how they look. In an interview with Scientific American, Thorne stated that the black hole in Interstellar was “by far the most accurate portrayal of a black hole that’s ever been put on film”. 

Christopher Nolan has defended the science behind the film, while admitting that many of the phenomena are deliberately speculative.

Since wormholes are theoretical, there is no guarantee of how they would appear, but after Warner Bros. licensed the code behind Interstellar’s rendered images to actual scientists, groups like the American Journal of Physics confirmed the likely accuracy of the film’s depictions over existing models

According to Space.com, interstellar travel is technically possible, as there are no laws of physics that prohibit it. However, some say that interstellar travel is not possible and will likely never be. 

The distances between stars are vast, with the closest star to Earth being Proxima Centauri, which is 4.5 light years away. Current drive systems are unable to achieve more than a small fraction of the speed of light. The speeds required for interstellar travel in a human lifetime are far beyond what current methods of space travel can provide. 

According to Space.com, wormholes can be formed if two singularities in far-apart locations can be merged. However, such wormholes cannot form naturally. Beings that can control gravity and travel through the Bulk could create wormholes and cross space much faster than light.

Interstellar takes place in a dystopian version of Earth in 2067. The planet is dying, and astronauts set out on a mission to find a new home for humanity. 

The film opens on Earth, but not like the one we know. It looks like somewhere in the midwest of the U.S., but giant dust storms, crop blight, and advanced technology tip us off that we’re sometime in the near future. 

Earth’s future has been riddled by disasters, famines, and droughts. The agent of destruction is a blight fungus that is sweeping across the world, and has already destroyed wheat and okra as a crop. 

The spaceship Endurance’s destination is Gargantua, a fictional supermassive black hole with a mass 100 million times that of the sun. It lies 10 billion light-years from Earth and is orbited by several planets.

Some say that Interstellar is scientifically accurate in areas that most sci-fi movies ignore. Others say that the movie is beloved for its scientific accuracy. 

Here are some areas where Interstellar is considered accurate: 

• Black holes Some say the movie’s depiction of black holes is close to accurate and was ahead of its time. However, the Event Horizon Telescope’s website says the movie’s black hole appears to have reversed the brightness in the approaching and receding side of the disks. 
• Wormholes Some say the wormhole science in the movie is pretty sound. The movie used Kip Thorne as a consultant, who is considered the godfather of wormhole physics. 
• Einstein’s theory ArcGIS StoryMaps says that Interstellar stays remarkably true to Einstein’s theory. 

However, some say that Interstellar stretches the science to fit the story. For example, in real life, a planet would have to be impossibly close to a black hole to experience such extreme time dilation.

However, as the Event Horizon Telescope’s official website points out, the science of Interstellar slightly falters away from reality for aesthetic reasons. The main difference was that the movie’s version of a black hole appears to have reversed the brightness in the approaching and receding side of the disks
