Vyvyan: Vyvyan, Vyvyan, Vyvyan. Honestly, whenever anything explodes in this house it's always 'Blame Vyvyan'.

Question: The Prisoner from the opening sequence is credited as being played by Arnold Brown. Can anyone tell me what else Mr. Brown has been in? He appears very familiar for reasons unknown...
