Corin Redgrave’s major theatrical comeback following his heart attack was overshadowed by the news that his niece, Natasha Richardson, lay critically ill following a skiing accident. But John Dove’s rewarding production still went ahead. In this epistolary play by Christopher Trumbo, Redgrave plays the author’s father, the late, blacklisted Hollywood screenwriter Dalton Trumbo. Redgrave is mesmerising as the always witty and usually angry Trumbo who, though jailed, refused to submit to the McCarthy anti-Communist witchhunts. Catch it if you can.
