I thought you might find this film interesting. I think it’s rather wonderful, actually, though it’s silent and definitely pre-CGI. It’s also a bit dodgy on the science in a few places.
However, made way back in 1923 by Max Fleischer, The Einstein Theory of Relativity has to be one of the first science films ever made. Who can think of an earlier one?
P.S. Bonus points if you can name the soundtrack music!
