Entire generations of people have grown up and will grow up on Disney cartoons. Since 1923, Walt Disney company has been making cartoons with an interesting story and a good drawing. Such cartoons take years to create, in the process of creation, their plot can be repeatedly changed so that the viewer watches them with interest from beginning to end.
Drawing a complete cartoon, to start changing its script later is costly and silly, and all the work goes in vain. It makes more sense to create a draft, discuss it with the writers, and then draw it clean, right?
It seems so, but in life it’s different. An example from the world of presentations: you have been making slides for your boss all night, and in the morning you find out that he had a completely different story on his mind.
Guys from Disney studios have solved this problem a long time ago. In order not to waste resources on redrawing unapproved scenes each time, they introduced storyboards, that is, visualizing the script without special details.
