Burt Caesar investigates the curtain call -the ulterior motives of Shakespeare's jigs, the politics of the panto walk-down, even the agitprop refusal to take a bow. Directors Peter Brook and Jatinder Verma , actors Josette Bushell-Mingo , Roy Hudd and Richard Wilson , designers, historians and critics explore the moment when we move from performance back to our own lives, and what it means to take and receive a bow. Producer Julian May (R)
