Gambon is almost the only leading actor not to grace Yasmina Reza's "ART" at Wyndham's. But together with Simon Russell Beale and Alan Bates he gave a deliciously droll radio account of the role of Marc. And for the RSC he shared Reza's two-hander "The Unexpected Man" with Eileen Atkins, first at The Pit in the Barbican and then at the Duchess Theatre, a production also intended for New York but finally delayed by other commitments.
