Would a black hole really appear as a sphere like in Interstellar?

The science advisor for interstellar was Kip Thorne, who just shared the Nobel Prize in Physics for his modelling of the gravitational waveform emitted by two merging black holes. He had the movie studio run a relativistic ray tracing code to generate the images of the black hole (given a small accretion disk in place around it). The simulation was the most detailed of its type ever made, and resulted in the publication of 2 academic papers. It did not include magneto-hydrodynamic modelling of the material in the disc, and left out some effects such as doppler boosting, doppler shifting, and gravitational redshifting, but the Einstein ring around the black hole is entirely a result of the light travel paths around the black hole in accordance with GR. 

So yes!
