"Success is never final. Failure is never fatal. It is courage that counts." - Winston Churchill
Behind every great animated production, are thousands upon thousands of ideas that make the story a whole. The concept is what makes a movie, the first idea is what starts it all. Once the idea has the O.K to go on to a production, hundreds of people go to work and work off of that one sketch and idea. Going on to thousands of different tones and feelings for certain scenes or developing characters that make the movie rich.
When the production and character designers are creating ideas for the story, they learn not to become to attached to a certain concept, because it can be rejected, put on the back burner or just simply not used in the big picture. To make the story as wonderful as possible, only the best, well thought out ideas make the cut. In the grand scheme of things, all of the ideas that weren't used actually helped the story become what it is. It takes brave people to do what they do, to think of an idea and let it go if it doesn't work then move on to the next idea.
From the beginning to the end, from the first spark of an idea to a full length feature, it all starts with a concept.
