Interstellar's original ending was much different than the final cut....

Nolan’s early take on the ending, however, essentially cuts Cooper off inside the black hole. His script “had the Einstien-Rosen bridge [wormhole] collapse when Cooper tries to send the data back.”

The wormhole falling apart would have prevented Cooper from returning home or interacting with the tesseract, which, according to Nerdist, was director Christopher Nolan’s idea. Instead, his journey would have ended there, with Cooper sacrificing himself in the name of his cause. This also would have prevented much of the finished film’s concluding events—Cooper’s return trip, rediscovering his daughter, and stealing a ship to search for Anne Hathaway’s Amelia Brand would never have happened. Nolan does not mention, however, whether in that original ending, the data Cooper is collecting to send back to Earth would have made it out before the collapse.
