Advent Children - Voice Actors
Voice actors were used in the movie to play the parts of the characters. There were voice actors for both the Japanese and English language releases of the movie. I do not know if French and German voice actors were used for the respective versions of the movie, but it is unlikely. The list of Japanese and English voice actors is below, sorted in alphabetical order.
