Interstellar is not just one of the most mind-bending and beloved films of the last 20 years – it also has produced some of the wildest fan theories of any film in that time.
The Christopher Nolan film is probably his most loved outside of The Dark Knight and it continues to be screened around the world to this day, receiving a number of IMAX screenings later this year to capitalise on the huge success of The Odyssey.
Bar maybe Inception, the sci-fi classic is the Nolan film that is both most complex and most common for spawning crazy theories
Similarly to Inception most of these revolve around the ending. Interstellar’s ending may appear pretty straightforward on the surface unlike the Di Caprio thriller, but many of the theories absolutely turn it on its head (and one will make you see the film in a totally different light).
Plan A actually failed, but ‘They’ went back in time to fix it

The film’s ending centres quite largely around the shadowy ‘They’, future human beings who are able to live a fifth-dimensional existence.
They are the ones who send Coop back in time to be the ghost in Murph’s room, allowing him to move books on her shelf to communicate with her.
In the movie there is a Plan A and Plan B. Plan A involves finding a way to save all the humans on earth and Plan B is repopulating the species using 5,000 cryogenically frozen human embryos.
In the end, despite Plan A being written off as impossible, Coop’s communication with Murph makes this possible.
According to one theory though this only happened as a way for timelines to merge because, originally, Plan A failed and everyone on earth died. ‘They’ ended up sending Coop back through time to change this timeline, merging a timeline in which they succeeded with one in which they failed to create the future we see at the end where Murph meets with Coop. This leads perfectly into another hotly debated topic, but only one option seems obvious.
‘They’ are the future versions of the embryos from Plan B

This theory became popular on Reddit as there are theories that just about anyone is ‘They’. One suggests it’s actually Coop ascending when he becomes trapped in the black hole, others are absolutely mad, but the only one that makes sense is that the 5,000 embryos succeed, and eventually evolve to the point where they start being able to cross timelines and dimensions.
One comment on Reddit said: “As far as those 5th dimensional beings go, I got the feeling it was supposed to be a grandfather paradox. the Fifths were really humans from the future who had mastered grav tech so much that they could create a wormhole and a tesseract in the past. But of course, humanity wouldn't have been able to do that without Cooper going into the singularity and ended up in the tesseract in the first place..”
Coop actually fell into an alternate dimension where the plan worked

This theory is both simple and absolutely bonkers. The simple part is that, when you look at it, humanity was absolutely screwed in the film when Coop goes into the black hole.
Plan A was impossible, plan B was looking highly unlikely, but when he crossed the event horizon of a black hole Coop was sent to another world in which humanity survived and built Cooper Station.
Contrasting the state of the station he wakes up in with the seemingly downhill trajectory of humanity seems a low percentage chance, and so it’s possible he fell into another dimension entirely and that explains it.
Coop died in the black hole and he was ushering Murph to the afterlife in the ending

The best theory however has nothing to do with ‘They’ and is a very simple one: it suggests that Coop dies floating in space.
The theory goes that, when looking at Coop and Murph’s final scene no one in the room actually pays any mind to the long lost father of humanity’s saviour returning having not aged in the past 50ish years. If that really happened you may want to give them some space, but you’d surely respond in some way, right?
Following that logic the theory, which is surprisingly airtight, suggests that he actually is dead and the ending is him ushering Murph to reunite with him in heaven.
