Which actor portrayed Cooper in Christopher Nolan’s Interstellar?

Matthew McConaughey portrayed Cooper in Christopher Nolan’s Interstellar.

Cooper is a former NASA pilot and engineer who joins a space mission searching for a habitable world beyond Earth. The character is driven by concern for his children, especially his daughter Murph, while the film connects his personal story to larger ideas involving gravity, time, and humanity’s survival.

Interstellar was released in 2014 and features Anne Hathaway, Jessica Chastain, Mackenzie Foy, Michael Caine, and Casey Affleck. The screenplay was written by Christopher Nolan and Jonathan Nolan, with scientific consultation from physicist Kip Thorne.

McConaughey’s performance anchors the film’s emotional storyline, particularly its depiction of the unequal passage of time between Earth and distant worlds. The movie’s scientific concepts are dramatized for a broad audience, so its fictional treatment of wormholes, black holes, and time dilation should not be confused with a documentary account of space travel.
