Interstellar is a 2014 science fiction film directed by Christopher Nolan. Starring Matthew McConaughey, Anne Hathaway, Jessica Chastain, Mackenzie Foy and Michael Caine, the film features a team of astronauts who travel through a wormhole in search of a new habitable planet. Brothers Christopher and Jonathan Nolan wrote the film, merging a script Jonathan developed in 2007 with Christopher’s ideas. Christopher Nolan produced the film with his wife, Emma Thomas, and Lynda Obst. Theoretical physicist Kip Thorne, whose work inspired the film, acted as scientific consultant and executive producer. Warner Bros., Paramount Pictures, and Legendary Pictures co-financed the film, while Syncopy and Lynda Obst Productions served as production companies. Nolan hired cinematographer Hoyte van Hoytema and shot the film on anamorphic 35 mm and IMAX 70 mm photography. Filming commenced in late 2013 in Alberta, Canada; Iceland; and Los Angeles. Double Negative created the visual effects. Interstellar premiered on October 26, 2014, in Los Angeles and received wide release worldwide. In North America, it was released in film stock to theaters still equipped to project the format, before expanding to venues using digital projectors. It has been a box office success and has received generally positive reviews from critics, who gave particular attention to the film’s scientific accuracy, visual effects, and performances, particularly from McConaughey, Foy, and Chastain.
