The Role of the Chorus in Shakespeare

Derek Jacoby made a striking modern figure in an overcoat striding around the film set in Kenneth Branagh's film. Olivier in his film had the chorus as an Elizabethan figure on the globe stage, even as his film moves interestingly away from its early theatricality. Is the chorus a part which is doubled? It is certainly not enough stage time really to earn a day's pay. This is an actor who has to do something else in the play as well. But there have been some interesting, more significant doublings perhaps,. whether chorus is the Archbishop of Canterbury or the French king and Henry himself.
