Trevor Nunn’s expert eye for the performing arts may not be so sharp when it comes to visual art. In his new autobiography Grow Up, actor Keith Allen recounts a slightly embarrassing anecdote about the director. After paying £27,000 for a Damien Hirst painting, Nunn was dismayed when he met the artist at the 1998 opening of The Homecoming, in which Allen appeared at the National, and was told that what he’d bought had been painted by two children – Hirst and Allen’s sons, Connor and Alfie, then aged two and ten. Nunn had the last laugh, though; according to The Sunday Times, two years after Hirst’s confession, Nunn resold the painting for £45,000.
