Five years in the making and a decade in the dreaming, Game of Thrones: The Mad King sweeps onto the stage with a rumble of drums and the courage of its convictions. That dog, a manipulated puppet, is the sign of the love and care that has gone into the whole. Game of Thrones: The Man King isn’t as rich and dense as Shakespeare, though it owes him a clear debt and feels entirely at home in a place devoted to his work. But it is a remarkable achievement, wonderfully directed by Cooke and superbly acted by every member of the 35-strong ensemble. The result is a brilliant exhibition of how theatre can create magic.
