In the UK Beauty and the Beast gets a PG rating (requires parental guidance), whereas in Russia it has been given an adults only rating. This is for exactly the same film.
The reason is homosexuality. In Russia since 2013 it has been illegal to talk or give information to minors (children) about homosexuality. In the new Beauty and the Beast live action film LeFou and his handsome friend begin a loving gay relationship. This is too much for the Russian culture minister who has slapped this heavy rating on the film.
