Well I have to admit for episode one I organise my stag weekend in New York to coincide with the opening weekend. It was a fun weekend - though a long way from London for the weekend.
I did go to the cinema a few weeks earlier just to check out where to sit in the auditorium and found a long queue of people camped out ready to buy tickets when the box office opened.
More to do with publicity than actually needing to I booked by phone the day booking opened without any problems.
