12．Kenneth Williams is considered one of the greatest British comedy actors of the twentieth century．His voice was his outstanding gift； it virtually defined him as a（61）performer （perform）．Williams would often spend weeks（62）deciding （decide） how a character should sound and this"voice"determined his approach to each role．（63）But even after he had chosen his"voice"，he didn't always stick to it．（64）In the middle of a single performance，he would sometimes change（65）the tone or speed of his speech，for greater comic effect．While still a beginner，he felt he should be given the freedom to do as he wished on stage and often（66）ignored （ignore） his directors'instructions．This greatly annoyed some directors，who refuses（67）to work （work） with him．Sometimes，he would completely ignore the script（臺詞）and make up his own lines during a performance．Although he was proud of his ability to go"off script"he became extremely angry（68）when/if other actors tried to do the same，arguing that they were simply no good at it．Williams loved to make his audience laugh．When performing a scene（69）where there were few laughs，he would often make up（70）his own jokes，which always entertained the audience，but sometimes also ruined the scene．
