Part of the reason I love this movie is that Kip Thorne was a technical advisor. And as this paper shows, some new science resulted from the movie-making process.
For any non-scientists that are interested in this subject, he published a book about his work on the film that was quite interesting.
"There are no new astrophysical insights in this accretion-disk section of the paper, but disk novices may find it pedagogically interesting, and movie buffs may find its discussions of Interstellar interesting."
I liked the visuals, but I think the script was a disaster, and the movie itself was only middling.
To each their own.
