Which actor played Dr. Mann in Christopher Nolan’s Interstellar?

Matt Damon played Dr. Mann in Christopher Nolan’s Interstellar.

Dr. Mann is an astronaut who leads one of the earlier exploratory missions sent to assess potentially habitable worlds. The crew initially treats him as a heroic figure, but his desperation for rescue leads him to falsify data and endanger the later mission.

Matt Damon’s appearance was kept relatively quiet in the film’s marketing, making the casting a notable surprise for many viewers. Matthew McConaughey plays Cooper, the mission’s pilot, while Anne Hathaway plays Amelia Brand.

Dr. Mann’s name is a deliberate thematic contrast with his actions. The character is not the same as Professor John Brand, played by Michael Caine, who directs the Endurance mission from Earth. Interstellar was released in 2014 and received the Academy Award for Best Visual Effects.
