Christopher Nolan wanted an actor who could bring to life his vision of the main character as an everyman with whom "the audience could experience the story." He became interested in casting Matthew McConaughey after watching him in an early cut of the 2012 film Mud, which he had seen as a friend of one of its producers, Aaron Ryder. Nolan went to visit McConaughey while he was filming for the TV series True Detective. Anne Hathaway was invited to Nolan's home, where she read the script for Interstellar. In early 2013, both actors were cast in the starring roles. Jessica Chastain was contacted while she was working on Miss Julie (2014) in Northern Ireland, and a script was delivered to her. Originally, Irrfan Khan was offered the role of Dr. Mann but rejected it due to scheduling conflicts. Matt Damon was cast as Mann in late August 2013 and completed filming his scenes in Iceland.
