It is a pity they didn't spend comparable effort on the story. I thought it was a really disappointing film, especially after they banged on so much about how good the physics in it was (apart from the black hole rendering, it wasn't).

Did we watch the same movie? They got bunch of physics stuff right, like the water planet, the relative aging due to being near the massive black hole etc. Only thing that wasn't "correct" was the wormhole and especially the tesseract, but that was some creative writing which allowed for a nice twist. I enjoyed it, a nice scifi.

The title is basically nonsense. They're talking about the black hole in that movie.

What did you expect from the title? That they used Einstein's equations to render the actors? Of course it's the black hole.

And it's not even Einstein's equations

     The geodesic equations are not Einstein's equations.
     The code for Interstellar only had to ray trace on a fixed analytical background spacetime (Kerr metric),
     rather than solve partial differential equations for the metric itself.
