Kishimito-sensei mentions that even though he would have liked to write some scenes with Sakura's parents, he hasn’t had the chance to include them until now. In his mind, he had the image for Sakura’s parents, which include back-and-forth arguing matches, but he just never could find the right time to do so. With so much of the manga release, he thought nobody would have interest in them at this point, although he still decided for them to be in the movie.
