Interstellar co-screenwriter Jonathan Nolan recently revealed how his original screenplay for the sci-fi epic ended before his brother, also the film's director, Christopher Nolan rewrote it.
Please be advised the following contains SPOILERS about how the finished version of Interstellar ends!
Jonathan Nolan and the movie's science adviser/producer Kip Thorne were promoting the forthcoming Blu-ray release at Caltech’s Jet Propulsion Lab when Nolan was asked about its divisive, and to many befuddling, ending, which Jonathan is said to have jokingly replied, "You’ve got the wrong brother."
reports that Jonathan said his "much more straight-forward ending 'had the Einstien-Rosen bridge [colloquially, a wormhole] collapse when Cooper tries to send the data back.' So no tesseract (that was Christopher’s idea), no time manipulation, and no return home. Nolan didn’t elaborate on this point, but we might speculate that the original end to the movie was as dark and unforgiving as space."
Interstellar hits Blu-ray on March 31.
