REVIEW: The Ruling Class, Trafalgar Studios ✭✭✭✭

James McAvoy and Kathryn Drysdale in The Ruling Class at Traflagar Studios

James McAvoy is a true, blistering, white-hot star who lights up every moment he is on stage, whose smile and darting, impressive eyes can say whatever he wants them to say; utterly mercurial, hilarious and wild one moment, malevolent and disturbed in the next, then sad or insane or calculating or sexy – or all of those at once.
