No. Unlike other anime franchises, Beastars does not have a movie; not yet anyway. Besides, Beastars is a story-intensive series and any filler content that the studio produces as an original movie might degrade the experience. However, if they intend to go the Demon Slayer: Mugen Train route and produce a canon film, that’ll be exciting. This means the movie will be based on the manga and will not deviate from it.
