The actors and film crew know how popular movies are made. Most of the hottest movies today have some form of special effect or CGI in them. This is especially true for movies taking place on distant or fictional worlds. They often need the help of a blue screen to give the movie the effect that the director is going for.
Take Guardians of the Galaxy Vol. 2 for example. This video takes you behind the metaphorical curtain into what an actor or filmmaker would experience in a day on set in a world made up of blue screens. But no need to worry. No spoilers.
This is what a community of independent filmmakers and film school students dream to be a part of.
