REVIEW: Trainspotting, King’s Head Theatre ✭✭✭✭

Trainspotting at the King's Head Theatre, London

With the audience sat and stood around three sides, the action regularly erupts off the stage, from projectile soiled sheets to splashes of murky toilet water. At 65 minutes, it moves along at a cracking and sometimes disorienting pace that leaves you staggering out of the theatre feeling like you’ve been assaulted (but in a good way).
