In a recent television special aired on NHK, entitled "Owaranai Hito Miyazaki Hayao" (translated as "The Man Who Is Not Done: Hayao Miyazaki), famous Japanese film director and animator Hayao Miyazaki announced his plans to return with a brand new anime film. The Japanese anime film icon retired from directing films three years ago. The last film Miyazaki's studio, Studio Ghibli, released was "The Kingdom of Dreams and Madness".

Miyazaki was recently working on a short CG film titled "Kemushi no Boro" ("Boro the Caterpillar"), which was supposed to be made for the Ghibli Museum. The veteran animator expressed during the special show that he was satisfied with it as a short film, and so plans to develop it into a full-length movie, according to the Morning News USA. He also stated that he would probably take him at most five years to finish the project, saying he would be turning 80 years old by then. Miyazaki also thinks the film will be finished by year 2019, which will be perfect timing since the year after that will be the 2020 Olympics which will be held in Tokyo, Japan.

Toshio Suzuki, Studio Ghibli's producer, said Miyazaki will probably continue drawing storyboards until his death. Another comment from a staffer said this would make the film a huge hit, as stated by the Anime News NetworkMiyazaki also confirmed that he will continue to make short anime films for the Studio Ghibli Musuem which is located in Tokyo. He stated that the story of "Kemushi no Boro" was already planned for almost 20 years. He described the story as "a story of a tiny, hairy caterpillar, so tiny that it may be easily squished between your fingers."

Hayao Miyazaki is well-known for his famous works, such as "Laputa: Castle in the Sky", "My Neighbor Totoro", "Kiki's Delivery Service"," Princess Mononoke", "Spirited Away", "Howl's Moving Castle", "Ponyo", and "The Wind Rises".
