Goofs

Two characters sustain a fall from an ice plateau, on a steep ice ramp, onto a shadowy ice platform. A moment later, a panoramic shot shows them fighting on a very different place.

Immediately, after the death of Professor Brand, When Murphy is transmitting the message to Dr. Brand, she says, "I am very sorry for your loss." However, when Dr. Brand receives the message at the ship, it plays as, "I am sorry for your loss."

The drone that Cooper and his children are chasing has an antenna on top. But the one they catch does not have it.

When Cooper goes in Murph's room to say goodbye, his watch indicates something like 9 a.m. In the next scene, when he gives a watch to Murph, his watch indicates something like 8.20 a.m.

Cooper draws a schematic on the drawing board to depict a landing on a planet close to the black hole. Two scenes later, the drawing is different from the one first shown.

At 1 AU from Gargantua, Miller's planet would be traveling at roughly 0.99c. In the companion book, Kip Thrope explains that Cooper made use of Intermediate Black Holes (IMBH) of roughly 10,000 solar masses in order to match this velocity. However, using a top speed of 0.3 AU / month (the rate that Endurance traveled to Saturn), it would have taken at least three months in Cooper's time (proper time) for the ranger to travel from an IMBH that was just 1 AU away from Miller's planet to Miller's planet. Given the time dilation in the neighborhood of Miller's planet, roughly 15,000 years in Earth time is needed for this leg of the trip. Another three months from Miller's planet back to another IMBH gives a best case scenario of 30,000 years (Earth time) for a trip to Miller's planet and back.

The rocket launching from the underground facility was portrayed as a three-stage Saturn V booster. The rings of office windows in the silo would have been blown out on launch. The static test firings of the Saturn V's Rocketdyne F-1 motors at NASA's George C. Marshall Space Flight Center (MSFC) in Alabama were known to routinely blow out windows in downtown Huntsville well over five miles away.

This would be true if the windows were ordinary window glass. However, Professor Brand explained that the launch chamber itself was also both a centrifuge and space station, meaning that everything would be engineered to withstand the extreme conditions of launching into space. This coupled with the fact that NASA would also know about the history of windows being blown out, one can safely assume that the windows around the launch chamber are more than likely blast proof.

No one can survive the g-force necessary to produce 7 years of time dilation per hour. The trip to Miller's planet and back would also consume a prohibitive amount of fuel.

Harvesting machines appear in one scene, suggesting harvest is underway. Corn is not harvested when it is green. The plant has matured and the ears ready for harvest when the stalks and leaves appear dried-out, light brown in color or "dead" in appearance. Also: drought or "dust bowl" conditions would not produce the high stalks and robust rows of thickly-foliaged plants as portrayed in the film. The plants would appear sickly and short.

When leaving Earth, a three stage rocket is used to launch the Ranger and four people (and a robot). When leaving the water planet (with 1.3 times Earth's gravity) the thrust from Ranger is sufficient to lift 2 people (and a robot). The combined weight of the other two people would not be enough to combat the additional gravity.

Current satellite technology can not only measure things like waves and topography, but it can do it in very fine detail. Surely the Endurance would have had similar (if not more advanced) technology on board. As such, surely they would have noticed the massive, fast moving waves on Miller's planet long before they started the landing process. - But, time is passing on Endurance 7 years per hour compared to on the planet, over 61,000 times faster. The motion of the waves would not have been visible at all. Though, it still seems strange they didn't seem to consider that conditions in the planet's time frame could be drastically different than what they see from the ship.

Mann states that the air on his planet contains too much ammonia to be breathable, but that at the surface, "the chlorine dissipates", giving way to breathable air. Ammonia is comprised of one nitrogen atom and three hydrogen atoms, with no chlorine in is molecular structure. Mann, being a scientist, would have known this.

However, Mann was lying to make them think the planet was habitable and admitted to Cooper during the fight sequence that there was no surface.

Dr. Brand's process is not explained for The "Population Bomb." One person would be alone to set up farming, and shelter. It is unknown how many Embryos would be gestated in the first batch that Brand would have to raise alone until those children could help build a new society, and raise crops while teaching and raising the next generation. The 500 embryos would not be incubated simultaneously because there would not be enough food and resources. It is likely that Dr. Brand would be able to handle no more than two to four while doing everything simultaneously herself.

Cooper and Donald sit on their porch before Cooper's departure, drinking what appears to be beer, despite the fact that all crops except for corn (including ostensibly hops and barley, ingredients in beer) are not able to be grown.

Two words: corn beer.

When he meets the people of NASA, Cooper says the nearest star is 1,000 light years away. While the nearest star, in the Alpha Centauri system, is about 4.4 light years away, Cooper meant that it would take a ship 1,000 years to get there using the technology known at the time.

When Cooper first gifts the watch to Murphy, it is around 8:20. When Murphy throws the watch on the floor, the scene was obviously flipped because now it shows it is 3:30, plus the direction of the clasp is reversed from normal watches.

When Brand climbs onto CASE to rush her back to the Ranger, she's lying in the opposite direction when they start making their way back.

The waves on Miller's planet could not exist where the depth is only 1 meter. Ocean waves are vertical movements of the water which could not exist as shown. If there was horizontal movement of water the currents would be in excess of 1000 kilometers per hour in order to feed that wave of that height.

At 2h 9mins, during the spinning docking sequence, the G force appears to be forcing the two pilots to lean in different directions, instead of in the same direction. This is correct, as the spacecraft is spinning about its central axis and centrepetal force will act on the pilots in this way.

At 0:18:20 when they're leaving the car and rushing straight to the entrance door because of the dust storm suddenly there is another person helping them enter the building. But he didn't follow them inside he just walks away to the left side of the house.

According to the exterior views of the Endurance, the individual modules would have very high ceilings. To move between them you would have to climb a ladder and then crawl through a tunnel and climb back down a ladder.

This is not reflected in any of the scenes we see inside the Endurance.

When Cooper initiates their lander spin to match the Endurance damaged by Dr Mann's incomplete docking connection, Cooper's neck is bending in the opposite lateral direction from Brand's. When they synchronize rotation, there is a rotational velocity but no acceleration so their bodies shouldn't be pushed sideways, only away from their seats from the remaining centripetal force directed radially outward from their lander spinning about the center line of the Endurance's docking hatch.

When Getty is at the house with Murph to check on Coop's lungs, he notices Lois coughing. When he asks her how long she's had her cough, she replies off-camera "A while." However, her reflection can be seen in the window behind Getty, & as she says "A while", her reflection instead shows her coughing into her arm.

At the baseball game, right after Donald complains about not having hot dogs, Murphys spoken dialogue differs from her mouth movements when she talks to Cooper.

At the baseball game, when Murph says to Cooper, "You hate farming, dad," the audio is out of sync with her lips.

(at around 44 mins) Cooper empathizes with Dr Brand saying, "It's hard, leaving everything." We can see his mouth - although not in focus - is visibly moving before his dialogue.

When Dr. Mann attempts to open the airlock of the Ranger he is on while attempting to enter into the Endurance, there would be basic mechanical, electrical and electronic interlocks preventing him from opening the outer hatch of the airlock while there is still atmosphere in the airlock and there is an imperfect mating of the docking mechanisms. This basic component of airlocks became standard in the 20th century.

NASA would need the help of significant industrial technology in order to build the Endeavor and the other spacecraft needed for the Lazarus missions. All indications are most of Earth's industry, especially its high tech industry, is no longer operating by 2074 as shown by everyone driving vehicles that are at least 60 years old and the old drone that Cooper and his family caused to crash near their home.

Doyle dies on Miller's world because he does not get back to the ship in time. However this only happens because he inexplicably chooses to stand around and wait for CASE to rescue Brand instead of continuing to evacuate.

On Miller's planet, Brand ignores Cooper's order to evacuate immediately because she insists that they nest to retrieve Miller's data. But the planet was clearly uninhabitable due to the mountain sized waves caused by the black hole.

When Cooper has to reset all the automatic farm machines' GPS systems, this indicates that some agency, normally NASA, has been maintaining and replacing the GPS satellites as needed at a time when NASA is supposedly shut down and no longer existing. We know that NASA still exists, but is keeping its existence secret, so theoretically, it shouldn't be launching GPS satellites every so often. Indications are that most industry in the world has ground to a halt as well, shown by all the vehicles that are by this date, several decades old, so there wouldn't be much of a high tech industry available to build new GPS satellites.

Boom Mic visible in the rear-view mirror of the car when Cooper has said goodbye to his son and closes the car door.

In one scene where the older Murph takes the watch outside the box in her room, a boom mic is being reflected in the glass of the watch.

Considering how important the Lazarus and Endurance missions were to the future humans, it seems highly unlikely that they didn't realize the importance of TARS when it was found together with Cooper (Matthew McConaughey) near Saturn almost 80 years later. They would want to download the wealth of recorded data TARS would contain about the Endurance mission, not just dump it in Cooper's museum house.

During the docking crisis scene, CASE analyzes the Endurance's spin at 67-68 RPM, meaning the entire station should complete a little more than 1 rotations per second. However, the actual RPM observed by the viewers is significantly slower, closer to 20 RPM (or 1 rotation every 3 seconds).

While docking with the Endurance, Cooper calls out distances in feet. NASA uses the metric system, so he should have been calling the distances in meters. Of course, since it was a while since he worked for NASA, such mistakes were bound to happen.

When Cooper sees the second wave approaching and orders the others back to the spacecraft, he says "we're in the middle of a swell".. Actually the region between two wave crests is a "trough", not a "swell".. (Although the extreme urgency of the situation could have understandably contributed to his error.)

When on Cooper Station while sitting on the porch outside the farmhouse, TARS asks Cooper if "this is how it really was?" presumably about how it was back on Earth. However TARS was on Earth when they first met, and by inference, had been for a long time. He surly would have had first hand knowledge of how life was back on Earth.
