Negative checking is a process by which producers of film, television and radio programs will be able to ensure that the names of fictional characters can not be confused with real life people. For instance, during the making of the Inspector Morse series , the producers of the show had the opportunity to check the names of the characters in the program. The primary reason for this practice is to prevent any possible legal action for libel which could result.
