This Sunday at North London's Hampstead Theatre, Steven Berkoff is the subject of Connecting Conversations, a series of discussions between psychoanalysts and leading practitioners from other fields. For this event which, depending on your point of view, goes under the compelling or repelling title of Steven Berkoff, Up Close And Personal, will ask the maverick actor and director about the nature of evil, specifically in characters such as Shylock and Iago. It's a subject which Berkoff, who has threatened to kill a critic or two in his time, should know something about.
