New Line said it will quickly begin work on a script to put a film into production. Sanrio also granted film rights to other characters including Gudetama, My Melody and Little Twin Stars.

Hello Kitty presents potentially steeper challengers, though. She doesn't talk or, for the most part, change facial expressions.
