odd research

If you already own the artwork and character design, then I would suggest that you take advantage of the progress in computerized animation software and produce your own short preview of your proposed show. You can post it up on the internet with your contact information and try to reach potential buyers (all the major studios, agencies, and networks scour the internet daily looking for new talent).

Film production occurs in five stages:^[1]

• Development—The script is written and drafted into a workable blueprint for a film.
• Pre-production—Preparations are made for the shoot, in which cast and crew are hired, locations are selected, and sets are built.
• Production—The raw elements for the finished film are recorded.
• Post-Production—The film is edited; production sound (dialogue) is concurrently (but separately) edited, music tracks (and songs) are composed, performed and recorded; sound effects are designed and recorded; and any other computer-graphic 'visual' effects are digitally added, all sound elements are mixed into "stems" then the stems are mixed then married to picture and the film is fully completed ("locked").
• Sales and distribution—The film is screened for potential buyers (distributors), is picked up by a distributor and reaches its cinema and/or home media audience.

Development

In this stage, the project's producer finds a story, which may come from a book, play, another film, a true story, original idea, etc. After identifying a theme or underlying message, the producer works with writers to prepare a synopsis. Next they produce a step outline, which breaks the story down into one-paragraph scenes that concentrate on dramatic structure. Next, they prepare a treatment, a 25 to 30 page description of the story, its mood, and characters. This usually has little dialog and stage direction, but often contains drawings that help visualize key points.

The production designer creates the visual conception of the film, working with the art director^[5].

• The art director manages the art department, which makes production sets
• The costume designer creates the clothing for the characters in the film working closely with the actors, as well as other departments.
• The make up and hair designer works closely with the costume designer in addition to create a certain look for a character.
• The storyboard artist creates visual images to help the director and production designer communicate their ideas to the production team.
