I guess you can use Special:Contact/close-wiki and tell staff which wiki you want to be closed. However, you can also try merging the wikis if that would better suit this situation.

Also just because the "Home 2015" wiki has that url, doesn't necessarily mean that wiki is only allowed to add articles about the movie - they can still add sequel related things.
