Tonight and for the next two Sundays, PBS and Great Performances will continue the Shakespearean saga begun in The Hollow Crown with Richard II, Henry IV Parts I and II, and Henry V. Now we get the two parts of Henry VI (beginning tonight, concluding next week), followed by Richard III. In tonight’s Henry VI, Part I, Henry V is dead. Long live the King: And Henry VI should live long, because when he’s crowned king, he’s only an infant. Jump cut 17 years, and Henry VI is a young man, played by Tom Sturridge. Co-stars in this edition include Downton Abbey star Hugh Bonneville as the Duke of Gloucester, Laura Frances-Morgan as Joan of Arc, Adrian Dunbar as Plantagenet, Sophie Okonedo as Margaret, and Sally Hawkins as Eleanor.
