Everyone that hasn't seen this severely needs to. IMO it is both Nolan and Hans Zimmer's best work. It's also Nolan's most dissectable film, which is saying quite a lot.
It's awesome how accurate is to actual physics theory. Astrophysicist Kip Thorne, who was an executive producer (I think), calculated a lot of the events that take place to obey general relativity and what we know of spacetime.
TARS and CASE need their own spinoff.
I may have said this already in random topic or somewhere, I can't remember.
