This was created in February 2024 (at this moment, there are talks with writers for the show and no cast released). The book description of characters are included and actors and actresses to be suggested must suit the description closely (allowing costume and make-up, of course). The actors and actresses are preferably British and Irish, like the original movies and try to avoid original movie actors please (especially for the main roles). The child actors are stated to be new unknown actors. As for irrelevant small characters, I think it would be funny to have cameos from well known celebrities as well as actors. *June 2026 update: The confirmed casts have been confirmed.
