If your topic is about an anime film, it goes into the Just Anime forum. General Discussion is for topics that cover both anime and manga while it cannot be tied down to a single wiki page.
As for your request, are you sure it's an anime film? In the past, I seen requests from new users who found out it wasn't an anime or an anime film.
I haven't seen a lot of anime movies being a new anime fan. Hopefully, someone can help you.
