How many minutes long is Christopher Nolan's film Interstellar?

Christopher Nolan’s film Interstellar is 169 minutes long. That runtime equals 2 hours and 49 minutes, making it one of Nolan’s longest theatrical features.

The film’s length reflects its unusually broad scope. It begins with a near-future ecological crisis on Earth, follows Cooper and the Endurance crew through a wormhole near Saturn, and then moves between different planets, spacecraft, and time scales. The story also spends substantial time with Cooper’s children, especially Murph, whose life advances while Cooper is away.

Interstellar’s time dilation makes the runtime especially easy to confuse with the story’s internal chronology. On Miller’s planet, one hour corresponds to approximately seven years for observers farther from the black hole Gargantua. Although the audience watches a single film lasting 169 minutes, decades pass for characters elsewhere in the story.

The film was released in 2014 and stars Matthew McConaughey as Cooper, Anne Hathaway as Amelia Brand, and Jessica Chastain as the adult Murph. Its 169-minute runtime includes the extended space journey, the black-hole sequence, and the emotional reunion near the ending.
