Watch the trailer for the new documentary on Studio Ghibli's Hayao Miyazaki

For many, Studio Ghibli co-founder Hayao Miyazaki is known as Japan's Walt Disney, both for his lovable, open-hearted demeanour and the devastatingly beautiful, animated films he has made (My Neighbour Totoro and Spirited Away among them).

So when the Academy Award-winning master animator and filmmaker announced his retirement in 2013, it was news that was met with great sadness. And that was when filmmaker Kaky Arakawa started filming.

A celebration of Miyazaki's life and his legacy, Arakawa's documentary, "Never-Ending Man: Hayao Miyazaki" follows the  then-73-year-old through the struggles of retirement, stepping away from his passion and into finding a new one: CGI. It's since been confirmed by Studio Ghibli that Miyazaki has come out of retirement and is working on a new feature film, so it's not all bad news.
