Before Christopher Nolan joined the project, Steven Spielberg was attached to direct the movie 'Interstellar' and the script for his version was vastly different from the script for the final film.

Steven Spielberg left because he shifted his production company DreamWorks from Paramount to Disney. Christopher Nolan was recommended to the studio by Jonathan Nolan, his brother, who was the writer for the film.Here is a short summary of the script of the Spielberg version:The original script of the Steven Spielberg version of this movie depicts an almost entirely different movie. Some examples include Murph being a boy, no humans are first sent into space (probes are) and a probe leads Cooper to the hidden N.A.S.A. base, which is on a remote island in California where Brand and Cooper deep-sea dive for parts. Also, the robots are much more human-like, featuring hands and shoulders. TARS is sucked into space early on when the ship gets stuck between two black holes (Gargantua and Pantagruel, named for two French mythical giants) immediately after entering the wormhole. Afterward, the crew, including an additional member named Roth, only visit the ice planet, where they discover that a Chinese mission had been there around thirty years prior, and seemed to have vanished, until it is learned that they were killed by the radiation of a neutron star. The crew falls through the ice into an entirely different ecosystem with a living rearranging forest and colonial organisms that fight each other every night, compounding into larger organisms to reach a higher spot closer to the ice "sky" for sunlight in the day. After searching the area, they find an abandoned Chinese camp with an experimental black box that can control gravity, and are then discovered by Chinese robots who sabotage their return home with the box. The crew orbits a black hole for hundreds of Earth years before entering a second wormhole where they interact directly with the fifth dimension bulk beings who lead them to a four thousand-year-old space station built by the Chinese that's only a few hundred years old, due to space-time relativity, powered by a captured mini black hole that views galaxies as flat lines of light. The Chinese have built thousands of worm holes, and tried to travel back in time with the gravity technology to save all of Earth, but died in the process. Cooper returns to Earth, in the year 2230, to find a barren land with ice storms. He sits down prepared to die in the storm, then awakens in a manner similar to the movie, where he meets his great-great-grandson, rather than an aged Murph. After being bored with the new world, Cooper steals a ship to find Brand (the two had been intimate before Brand left Cooper, to continue to explore space, rather than return to Earth).I got this from the IMDB trivia page for the movie: https://imdb.to/2KscWh5 learned after the post was submitted that IMDB trivia is user submitted and hence may be erroneous. So do take point 2 (the Spielberg script) with a grain of salt. Everything I said in point 1 is tru though. via /r/movies http://bit.ly/2QMT5dB
