It may be a big year for Shakespeare — the fact he fell in love brought him several Oscars (albeit posthumously), and his “A Midsummer Night’s Dream” and “Titus Andronicus” are due in movie theaters soon — but his birthday has been left out of (of all places) the Royal Shakespeare Company’s official datebook … because he is not deemed famous enough. While the births of Martin Luther King and George Washington gain a mention in the RSC’s 1999 calendar, the world’s greatest playwright is missing. RSC spokeswoman Kate Hunter said: “We have asked a number of companies to include Shakespeare in our diary, but they have refused. We really do hope this will change — after all, he was voted the BBC’s Man of the Millennium.” For the record, Shakespeare was born in 1664 at the end of April. The exact date is uncertain.
