If you watch a lot of movies and TV as I do (and occasionally even make them), you’ve probably sometimes wondered “How did they do that”? Well, as you’ll see from this video, they “did that” with a lot of green screen and visual effects.
Visual effects is a huge part of Hollywood and the men and women who work in that industry should be recognized and rewarded as such. This is only a small fraction of the work they do each and every day.
Enjoy and try not to be too shocked.
