Warner Bros. produced the DVD and Blu-ray versions of Interstellar, while Paramount distributed the film. Two books were produced about the science behind the film, one by Caltech physicist Kip Thorne and another that Thorne consulted on. Gregg Landaker and Gary Rizzo mixed the film's sound, while Richard King supervised and Christopher Nolan paid close attention to sound design. Composer Hans Zimmer scored the film, developing a unique sound with Nolan by avoiding typical string and drum instruments and scoring in 45 sessions, three times more than for Inception.

3. Who produced books for interstellar?
• In "The Science of 'Interstellar'" (W.W. Norton & Company, 2014),
Caltech physicist Kip Thorne takes readers on a short swim through
the very deep physics that underlies some of the amazing sights from
the movie: black holes, higher dimensions and 4,000-foot-tall (1,200
meters) waves.
• Thorne joined the "Interstellar" project in 2005, when it was just a
seed of an idea by producer Lynda Obst, Thorne's long time friend.
Thorne stayed on board throughout the production of the movie, and
worked as a science consultant for screenwriter Jonathan Nolan and
director Christopher Nolan.

4. Sound design and music
• Gregg Landaker and Gary Rizzo were sound engineers for the film, tasked
with sound mixing, while sound editor Richard King supervised the
process.
• Christopher Nolan said he sought to mix the film's sound to take maximum
advantage of current sound equipment in theatres. Nolan paid close
attention to designing the sound mix, for instance focusing on what
buttons being pressed with astronaut-suit gloves would sound like.
• The studio's website said that "The sound on Interstellar has been
specially mixed to maximize the power of the low end frequencies in the
main channels as well as in the subwoofer channel." Nolan deliberately
intended some dialogue to seem drowned out by ambient noise or music,
causing some theatres to post notices emphasising that this effect was
intentional and not a fault in their equipment.

5. Sound design and music
• Composer Hans Zimmer, who scored Nolan's Batman film trilogy
and Inception, also scored Interstellar. Zimmer and Nolan strived to
develop a unique sound for Interstellar. Zimmer said: "The textures, the
music, and the sounds, and the thing we sort of created has sort of seeped
into other people's movies a bit, so it's time to reinvent. The endless string
need to go by the wayside, the big drums are probably in the bin." Zimmer
also said that Nolan did not provide him a script or any plot details for
writing music for the film and instead gave the composer "one page of
text" that "had more to do with [Zimmer's] story than the plot of the movie".
Nolan has stated that he said to Zimmer: "I am going to give you an
envelope with a letter in it. One page. It's going to tell you the fable at the
center of the story. You work for one day, then play me what you have
written", and that he embraced what Zimmer composed. Zimmer
conducted 45 scoring sessions for Interstellar, which was three times
more than for Inception. The soundtrack was released on November 18,
2014.
