It was the 'naughtiest' film ever to apply for a Production Code Seal of Approval. The film contained 4 letter words and other "adult content". It starred Elizabeth Taylor and Richard Burton.

Warner Brothers promised to only allow those over 18 to see the movie, and the Hays Office, the censor body, relented.

Movies had been censored on a code introduced in 1930 which demanded that they don't "lower the standards of those who see it."

Movies were heavily influenced by this code until it was replaced in 1968 by a movie ratings system:

• category G (for general audiences),
• MGP (all ages admitted but parental guidance suggested), and
• R (no one under 16 admitted)
