Despite retiring from feature films, Hayao Miyazaki is not taking a break from animation completely. It's been revealed that he will be embarking on a new project, expected to take him 3 years to complete.
His son, Goro Miyazaki said “He gets bored when his goal is maintaining [the Ghibli Museum], so he needs things to fiddle around with.”
The animation is expected to be a 10 minute offering, which will take 3 years to complete (that's a lot of fiddling, but we'd expect no less from Hayao Miyazaki). It will feature a caterpillar and be created with 3D CGI technology, which is a departure from Miyazaki’s usual hand drawn style.
There’s no word yet on whether the animation will be kept at the Ghibli Museum, or whether it will be available to a wider audience.
His last project was "The Wind Rises" which was completed in 2013.
