Interstellar
You might be surprised to learn that Interstellar was filmed without the use of green screens. Nolan shot the entire film on a single handheld IMAX camera. Although the film does indeed take place in space (and beyond), Interstellar largely avoided CGI in favor of detailed physical sets and 60-foot projections of space on the set backgrounds. Despite this, or perhaps because of it, the film won an Academy Award for Best Visual Effects.
The visual effects team wrote a rendering of software based on the equations of an actual astrophysicist in order to create Interstellar's black hole. Some individual frames took up to 100 hours to render. "Chris really wanted us to sell the idea that the black hole is spherical," said Paul Franklin, the film's visual effects supervisor.
