Many famous directors, from Alfred Hitchcock to Steven Spielberg, never dreamed of making their classic films without first utilizing a storyboard artist, helping to plan their vision based on the script. They carefully structured their ideas by drawing them on paper, long before a single frame of film was ever shot.
Storyboards tell a story – visually. Their purpose is to sequentially tell the story of the main character reach his destination from point A to Z. There’s an old saying that if a movie is well made, you should be able to turn-off the volume and still be able to follow what’s happening in the movie by what you’re seeing. The pictures are telling the story. Storyboards help achieve that.
