I saw his Lear at Chichester a few years back, a beautiful performance, a Lear who genuinely was approaching four score years. I was too young to have seen his Hamlet, a performance that was still being talked about years later. But he is in Peter Hall's Dream as Lysander (a role that I've always seen as rather underwhelming) and holds his own in a very strong cast.
I wish he hadn't disappeared from the stage for so long: I'd love to have seen his Richard III or Iago, but it was not to be
Brilliant in Cross of Iron. He portrayed 'sardonic' brilliant in almost every film he was in!
