An animated film adaptation of Tatsuya Miyanishi's popular You Are Umasou (Omae Umasou Dana) picture book will open in Japan in October. The story centers around a Tyrannosaurus who comes across an Ankylosaurus baby all by himself and says, "Gaō! Omae Umasou Dana" ("Rawr! You look delicious.") However, the Tyrannosaurus ends up adopting the baby as his own.

8-year-old Seishirō Katō will play the role of the herbivorous Ankylosaurus boy. The official website of Japanese singer Ayaka Hirahara (The Story of Saiunkoku) announced in a Friday update that her "Kimi to Iru Jikan no Naka de" song with be the film's ending theme. 1.5 million copies of the book have been published.
