U films are suitable for all ages, while PG films may contain scenes unsuitable for young children; 12A/12 films are restricted to those 12 and older unless accompanied by an adult, and 15 films are only suitable for ages 15 and older. The 18 rating is restricted to adults, featuring content that may include strong violence, drug use, and sexual references.
