This is one of those plays where within a few seconds, you’ll turn to the person next to you, Malteasers falling from your gaping mouth, and say: that shouldn’t be possible! Bright yellow cat-shape school bus whizzing round stage? No problem. Gigantic puppet of Totoro snoring with the vigour of a middle-aged man named ‘Keith’? Consider it done. The play rises to the challenge of bottling the magic, heart and amazement of every great Ghibli film.
