In 1965, Miyazaki joined Takahata and animation director Yasuo Otsuka in making a full-length feature titled “The Little Norse Prince Valiant (Taiyo no Oji Horus no Daiboken)”. Eager to make a film able to compete with the TV cartoons that were killing off the market for animated features, Takahata and Otsuka opened their creative brainstorming sessions to all members of their team, regardless of company rank or experience. Miyazaki jumped at the chance.
