附上2011年时Kay对舞台化的寄语(此访谈的时间应该是2012年),我试图翻译过不过怎么看都是语死早于是只有这个有英文原版所以自己看吧

原文:I am delighted that PHANTOM is to be dramatised by Studio Life. THE PHANTOM OF THE OPERA has been dramatised many times in the decades since the story was first published, both in film and musical format. There have been many differing interpretations of the story, ranging from pure horror to high romance and the central character of the PHANTOM has been altered accordingly to reflect the genre of each particular adaptation. This will be the first dramatic work to focus principally on the formation of the character of the PHANTOM and to understand the forces that shaped him into one of the best known characters of stage, screen and book. We are all products of our past and PHANTOM is the back story of one of the great fictional icons of our time. It seeks to portray a man who became a villain in so many ways and yet, in the words of his original creator, Gaston Leroux, had “a heart that could have held the empire of the world”. It is for that heart that the world has come to love the man known as THE PHANTOM OF THE OPERA and to care about his tragic story.
