The document discusses the 12A and 12 film rating classifications in the UK. It explains that 12A films can be seen in cinemas by children under 12 only if accompanied by an adult, while 12 rated films cannot be sold or rented to those under 12. It also notes that while 12A content is suitable for ages 12 and over, very young children may still find some elements upsetting. The tone and frequency of horror or disturbing elements in a film can impact its rating between 12A and 15. Some examples of horror films that received 12 or 12A ratings are provided.
