The film was first announced on September 21, 2016 when the finale of the anime's fourth season, Fate/kaleid liner Prisma Illya 3rei aired. Shin Oonuma and Silver Link returned from the anime series to direct and produce the film, respectively.^[2] Singer ChouCho performed two theme songs that are played in the film's ending primarily centered around Shirou's actions and his bonding with Miyu.
