Allan Little talks to the acclaimed actor, writer and director Steven Berkoff. He’s spent over 50 years in the theatre and on film, rocking the establishment with his outspoken and often angry views. His work ranges from appearances in A Clockwork Orange and The Girl with the Dragon Tattoo; to adaptations of Franz Kafka’s Metamorphosis. He has also written a number of his own plays – one of which he appeared in at this year’s Edinburgh Festival Fringe. He believes the art world is letting audiences down by abandoning serious, quality drama to pursue mass audiences. So what is theatre – art or entertainment?Picture: Steven Berkoff, Credit: Stuart Wilson/Getty Images
