Although he announced his retirement three years ago, animation legend Hayao Miyazaki has now confirmed that that's no longer the case.

As part of a TV special by NHK, Miyazaki - who is now 75 years old - admitted that he is not yet done with his incredible and groundbreaking works. According to the special, Miyazaki had begun work on a CGI short film for the Ghibli Museum in Tokyo, Japan, and found that he wasn't satisfied working on such narrow parameters.

His 2003 film, Spirited Away, is the highest-grossing film at the Japanese box office and won the Oscar for Best Animated Film that year in competition against Disney's Lilo & Stitch and Treasure Planet amongst others.

Miyazaki's first film since his retirement will be Kemushi no Boro - or Boro The Caterpillar in English, a film that he has reportedly been working on for twenty years. It's said that the film will take just over three years to complete, most likely just in time for the 2020 Olympics in Tokyo.
