Knock Knock No one younger than 18 may see an 18 film in a cinema.

Adults should be free to choose their own entertainment. Exceptions are most likely in the following areas:

  • where the material is in breach of the criminal law, or has been created through the commission of a criminal offence
  • where material or treatment appears to us to risk harm to individuals or, through their behaviour, to society. For example, the detailed portrayal of violent or dangerous acts, or of illegal drug use, which may cause harm to public health or morals. This may include portrayals of sadistic violence, rape or other non-consensual sexually violent behaviour
  • which make this violence look appealing; reinforce the suggestion that victims enjoy rape or other non-consensual sexually violent behaviour; or which invite viewer complicity in rape, other non-consensual sexually violent behaviour or other harmful violent activities
  • where there are more explicit images of sexual activity in the context of a sex work (see right) In the case of video works, which may be more accessible to younger viewers, intervention may be more frequent than for cinema films.

2nd July 2015

This week Jurassic World lost its 2 week hold at the top of the UK box office and made way for those little yellow people as Minions makes its debut.

Taking over the number 1 spot with a very good weekend gross of £11.5 million and it is clearly looking to repeat the success of Despicable me 2 for which the Minions became famous.

Despicable Me 2 was released at about the same time in 2013 and took £14 million on it's opening weekend, it did become the top grossing film of that year.

Jurassic World fell a single place on it's third weekend of release but the film is still going great guns and is now the top grossing film of the year with £48.9 million.

Other new films this week are Knock Knock from Eli Routh at number 7 and Slow West at number 10.
