Makoto Shinkai Working on New Movie in 2015

Makoto Shinkai's blog announced at the end of last year that he is working on a new movie. The director spent New Year's Eve drawing storyboards and said he hopes the new film will be more fun, more beautiful, and that it will surpass his other works (Kotonoha no Niwa, Byousoku 5 Centimeter, and more). While no title or release date has been announced yet, Shinkai said he would dedicate all of his time to this new movie in 2015.
