And this time it is BBC bosses who are feeling the wrath of John Cleese. The Fawlty Towers star has launched a stinging attack on executives at the broadcaster by claiming they do not know how to make comedies. The 73-year-old told how bosses with no experience of making comedies liked to interfere in TV shows. He said executives in the 1960s and 1970s had experience of producing and directing comedy. But, according to The Sun, he added: 'Now there seems to be an executive class and they have never written and never directed. They seem by some mystical process to understand comedy much better. And now they want to know what is going to be in every programme so that they can say: "That won't work." Cleese also said that entertainers had much more creative freedom when he started in the industry. The latest outburst is a series in a number of controversial comments by the comedian. He once told of his 'dreadful' mother Muriel and that she had lived to 101 but he thought he would never get rid of her. Two years ago, he also said that London was no longer an English city. Cleese's outburst was for a farewell show about BBC Television Centre, which is being shown on Friday. The site is being sold off by the BBC for £200million and being redeveloped into shops and offices.
