Interesting Fact - Films
80% of Alfonso Cuarón’s film Gravity was composed of digital shots. (Basically this wasn't so much adding special effects to a film, as the special effects being the film. Each frame took around 50 hours to render fully and if the entire film had been rendered using a single CPU processor, it would have taken about 7,000 years to complete. We have come a long way since Fantasia.) You can read more about the amazing work that went into this film here: https://www.fxguide.com/featured/gravity/
