McConaughey 'extraordinary' in Interstellar, says director Nolan

Director Christopher Nolan, who is notoriously secretive about his projects, has said Matthew McConaughey is "extraordinary" in new movie Interstellar.

Nolan revealed he was desperate to hire the recent Oscar winner to star in his new sci-fi thriller - which co-stars Anne Hathaway, Jessica Chastain and Michael Caine - after seeing him in critically acclaimed indie hit 'Mud'.
