The cinematic language is universally understood across continents. Without words, the visuals in movies (and TV, for that matter) should tell us a story. We can see hope, fear, love, and excitement in a character's face. The camera can move in ways that tap into our inner emotions and reveal huge plot points just by pointing at something or panning to it.
As we've said many times here, and as you've heard many times before, cinema is a visual language.
Filmmakers use visuals to communicate the story to the audience and to move them through certain emotions. No matter what your job is within filmmaking, your goal is to make sure the visuals all communicate the filmmakers' intention. That goes from writing to producing to editing to acting—it adds to one goal.
And that goal is to create magic.
