Film-maker Phil Grabsky on David Hockney

Painter David Hockney is regarded as Britain's most popular living artist even if he's spent a huge chunk of his long life in America. The 80 year old is still prolific and still experimenting after six decades of producing distinctive brightly coloured, often large scale landscapes and portraits. In 2016 he produced 82 portraits, each one painted over just three days, for an exhibition at the Royal Academy of Arts in London. Just four years earlier he'd mounted a exhibition of landscapes at the same venue. These two landmark exhibitions form the heart of a new film about David Hockney, the latest in the Exhibition on Screen cinematic series that until now has concentrated on artistic geniuses from the past. The series, now in its 5th year, is driven by filmmaker Phil Grabsky.
