Legendary anime film director Hayao Miyazaki is set to come out once again from retirement to direct one more animated feature film.

Back in 2013, Miyazaki announced that he would be retiring to concentrate on smaller projects like book covers and short films, rather than a full-length feature. A year later, he was awarded an Honorary Academy Award for his contributions and impact on film and animation.

However, the "Spirited Away" director revealed that he is not satisfied with the 12-minute CG short film that he was creating for the Ghibli museum - "Boro the Caterpillar" and instead wants to expand it to a feature-length film. He made this announcement on an appropriately-titled special TV broadcast named "Hayao Miyazaki: The Man Who Is Not Done," a documentary of his post-Ghibli days.

The documentary tells views about how his work after the dissolution of Studio Ghibli back in 2014. In one scene, Miyazaki uses a digital drawing tablet for animation, an entirely new concept to him compared to traditional animating. At the end of the broadcast, his announcement, as well as a pre-production schedule has been revealed.

"Boro the Caterpillar" will be his first ever feature film project in full CG. While there is no green light from Studio Ghibli producers themselves, Miyazaki is now starting to work with its animation, The Verge says. The story, Miyazaki said, will be about "a tiny, hairy caterpillar - so tiny that it may be easily squished between your fingers".

The film is targeted to be released on 2019, just a year before the 2020 Tokyo Olympics. With Miyazaki being 75 years old, Studio Ghibli producer Toshio Suzuki says Miyazaki might die during the production of the film, in which Miyazaki replied: "I think it's still better to die when you are doing something than dying when you are doing nothing. It's better to think about not dying when you die."

Miyazaki is the co-founder, director, and animator of Studio Ghibli, and has since released several award-winning films like "Princess Mononoke," "Spirited Away," "My Neighbor Totoro," and "Howl's Moving Castle."
