“There’s nothing more important than the initial inspiration. That’s how it was with ‘The Girl Who Leaped Through Time’ and ‘Summer Wars’ as well […] filmmaking is all about believing in the strength of the inspiration that struck you to drive the project right up to the completion of the production. There are times when what you believe in gets kind of paralyzed due to the lengthy process and the amount of efforts involved in the production of an animation film, but all you can do is to keep believing what you are doing is the right thing.” --Mamoru Hosoda
