Funimation had a ton of announcements at Anime Expo and this one was no different. They announced that Love Live! Sunshine!!! The School Idol Movie Over the Rainbow will come to U.S. theaters on August 5. The movie is scheduled for a Japanese home release on July 26 with English subtitles for those of you who don’t want to wait and import it.
Screening locations for the movie with a title longer than most light novels have not yet been determined; however, Funimation does have a website set up that you can check for when screening locations become available: https://www.funimationfilms.com/movie/love-live-sunshine-the-school-idol-movie-over-the-rainbow/
