This is Whishaw’s show – no question. He is a force of nature, fiercely unearthing every moment of nuance, humour and purpose from the text and giving a totally committed, undeniably powerful and persuasive performance. Every moment is fascinating, thought through and skilfully played. Dionysius was the God of the theatre, as well as wine, song and dance. Whishaw makes this part of the very fabric of his turn as the vengeful God, and offsets that performance with two remarkable cameos – as Tieresias and the Messenger. He is magical in every way.
