Michael Billington: “I’m delighted that Black Watch won four awards. But this is a show that opened in Edinburgh in the summer of 2006, has been seen all over the UK and the world, and is only now eligible for an Olivier because it did a season at the Barbican. … If we are to have London-only awards (which is debatable), they should at least be wide-ranging enough to include West End, off-West End and fringe theatres in acknowledgement of the capital’s diversity.”
