"Although all studios are now moving towards digitalization, a foundation in which we draw pictures by hand hasn't changed, so I foresee that we will continue to keep it in the future. After all, we used the digital method based on a conception of expanding and advancing the expression of the traditional animation cel in Steamboy. The first goal of this project was to overcome limitations of camera angles caused by platforms. On that aspect, I won't go back to the traditional method. I hoped to combine the merits of the traditional method of cel animation with the merits of the new CGI method."
