In Mirai, a 4-year-old boy has trouble coping with the changes in his family when a baby is born, with him no longer being the centre of everyone's attention. But then a magic gate opens in the family's backyard, and going through it allows the boy to see glimpses of family members in the past and future, teaching him to become a better brother to his little sister.
Variety was the first to break the news about Mirai, and even managed to interview Hosoda Mamoru about the film and what influenced him.
Hosoda's own Studio Chizu will be making the film, and it's planned for release this time next year. Newly-launched sales house Charades will handle international representation.
