Case Study - Alien

In 1979, Ridley Scott directed the widely known cult classic "Alien". In modern days this film would be regarded as relatively mild, although upon release there was a level of controversy over considered age ratings. British distributors urged the BBFC to grant the movie an "AA" which today would be equivelant to a fairly mild 15. Yet upon further consideration the BBFC rated "Alien" an "X" due to the reasoning that other future films of the same level of violence would also have to be regarded as an "AA" diminishing the name of the BBFC.
