Though I understand its problems, I still enjoyed the visual ride that was Interstellar. Still, the best thing about the movie might have been the TARS and CASE moving monolith robot machines. Here’s a behind the scenes clip that shows how the practical effects of TARS and CASE were made and how they were controlled and moved and given life by puppeteers.
It’s fascinating to find out the inspirations behind TARS and CASE and also so very impressive to see the puppeteers move those 200 pound stainless steel things around. It all adds up to a great combination of practical effects, human skill and CGI.
