An eagle-eyed TikToker has found a clue in sci-fi epic Interstellar that changes the meaning of the entire movie. Directed by Oscar-winner, Christopher Nolan , the movie explores themes as diverse as quantum physics and black holes, to death and time travel . Starring Matthew McConaughey as Joseph Cooper, as he tries to reunite with his daughter Murphy , the 2014 blockbuster was one of the year’s highest-grossing films at the time.

It has amassed a cult following for both theories around its meaning and its soundtrack composed by Hans Zimmer. Cooper travels through time and space to come back home to “Murph” but Nolan fan @Stark_Verse believes the Oppenheimer and Dark Knight director has left a clue in the movie that unravels its entire meaning. “I just rewatched Interstellar and I noticed what seemed like a mistake,” he began.

“I just cannot unsee this.” He shares clips from the movie that are seemingly reused. The first is of an aircraft at the beginning of the film when Cooper has his crash dream sequence, the clip then appears to be repeated an hour into the film, when his crew are entering Miller’s planet’s atmosphere.

“So the same footage is being used twice, in completely different contexts,” he explained. “It’s the exact same footage, and at first I thought this was a simple mistake but then I realised this is Christopher Nolan, Christopher Nolan wouldn’t use the same footage without a purpose right? It didn’t make sense until I looked at.
