If you were one of those people who struggled to get your head around the ending of Interstellar (of which there are undoubtedly many), you may have been more satisfied with the original ending.
Jonathan Nolan, who co-wrote the script with brother and director Christopher, has revealed that his original ending was "much more straightforward".
Nerdist.com reports that Nolan, speaking to scientists in California at an event promoting the Blu-ray release of the movie, joked, "You've got the wrong brother" when was asked to explain the final cut ending.
The real ending sees Cooper (Matthew McConaughey) heading into the black hole where he hopes to send data back to earth. However, he finds himself inside a 5th dimenional tesseract within which he can go back in time and contact his young daughter before he finally returns to the present to meet his aged daughter (even though he has not aged himself).
Jonathan revealed that the original ending was much simpler, and much more bleak.
Nerdist reports, "Jonathan Nolan’s much more straight-forward ending 'had the Einstien-Rosen bridge [colloquially, a wormhole] collapse when Cooper tries to send the data back.'"
This would mean that the happy ending which saw Cooper reunited with his daughter before returning to space to find Anne Hathaway would not have happened as he would have been trapped in the black hole.
