Keiko Kitagawa
The voice cast for the film "Magic Tree House" was announced on 8 August 2011. In her voice-acting debut, actress Keiko Kitagawa described this role as "challenging", and he added that she "wanted to express the freshness of the voice of [Jack] as much as possible." Mana Ashida, an avid reader who is a big fan of the original book series, said that she was "highly motivated" to play the role of Annie in this film. She said that she "enjoyed the adventure as much as Annie", to the extent that she felt that "she was flying into the book to be with Annie." Mana Ashida had previously voiced Agnes in the Japanese version of the 2010 film "Despicable Me".
