On 23 April 2016, Charles appeared in a comedy sketch for the Royal Shakespeare Company's "Shakespeare Live!" at the Royal Shakespeare Theatre, to commemorate the 400th anniversary of William Shakespeare's death in 1616. The event was televised live by the BBC. Charles made a surprise entrance to settle the disputed delivery of Hamlet's celebrated line, "To be or not to be, that is the question". Prince Charles is an author of several books that reflect his own interests. He has also contributed a foreword or preface to books by other writers and has also written, presented and has been featured in documentary films. Since his birth, Prince Charles has undergone close media attention, which increased as he matured. It has been an ambivalent relationship, largely impacted by his marriages to Diana and Camilla and its aftermath, but also centred on his future conduct as king, such as the 2014 play "King Charles III". Described as the "world's most eligible bachelor" in the late 1970s, Prince Charles was subsequently overshadowed by Diana. After her death, the media regularly breached Charles's privacy and printed exposés. In 2006, the prince filed a court case against the "Mail on Sunday", after excerpts of his personal journals were published, revealing his opinions on matters such as the transfer of sovereignty of Hong Kong to China in 1997, in which Charles described the Chinese government officials as "appalling old waxworks". Mark Bolland, his ex-private secretary, declared in a statement to the High Court that Charles "would readily embrace the political aspects of any contentious issue he was interested in ... He carried it out in a very considered, thoughtful and researched way. He often referred to himself as a 'dissident' working against the prevailing political consensus." Jonathan Dimbleby reported that the prince "has accumulated a number of certainties about the state of the world and does not relish contradiction." Other people who were formerly connected with the prince have betrayed his confidence. An ex-member of his household handed the press an internal memo in which Charles commented on ambition and opportunity, and which was widely interpreted as blaming meritocracy for creating a combative atmosphere in society. Charles responded: "In my view, it is just as great an achievement to be a plumber or a bricklayer as it is to be a lawyer or a doctor". Charles's anguish was recorded in his private comments to Prince William, caught on a microphone during a press photo-call in 2005 and published in the national press. After a question from the BBC's royal correspondent, Nicholas Witchell, Charles muttered: "These bloody people.
