I also wondered where Diana Rigg was. Well, I wondered for a couple of seconds and then became so overwhelmed with the entire experience, I've completely forgotten about her (until now).
I don't even know what to say about the celebration itself, it felt so unreal to be there and it still does. Especially since I never thought I'd be there in the first place and am not entirely sure how I ended up with a ticket. I passed by the NT in the morning just in case, only to see the ''No Day Seats'' notices all over the main entrance. But being the psycho I am, I decided to return in the evening to see who's there and at least feel a bit of the atmosphere surrounding it. So, there I was in the hall sipping my drink (in order to look less of a gawking fangirl loony), feeling rather happy I'd got to see the likes of Tom Stoppard, Trevor Nunn, Maureen Lipman, Imelda Staunton in flesh (plus various younger WE actors), and was about to go home when I spotted a small group of dressed-down people in a corner. They looked pretty out of place and in the company of an usherette, so I decided to approach them to see what it's all about. All I could make through the noise (and slight alcohol haze - they seem to pour a decent amount of gin in G&T at the NT) was the usherette telling them to wait until everyone had got in and then to head to the top of the Olivier circle. I still thought they must be the ballot winners or some kind of NT volunteers or theatre students or something and they actually had tickets, but nevertheless I couldn't leave without giving it a try. And when the hall was almost empty and the usherette came back with a bunch of tickets she started handing out to the group, I think I must have had a little bout of insanity since I just grabbed one and started running up the stairs as fast as I could with my drink and all. So I got a seat, got the free brochure and watched the show.
I still have no idea who those people were and why they got free tickets. The ticket I have says ''Filler'', but two things still puzzle me - why they weren't sold as day seats, and how those people knew free tickets would be handed out?? I noticed some of them clutched a printed copy of the Olivier seating plan - a mystery.
Oh, and after the show, there was some kind of a cocktail organised in the hall - I ate some mini-quiches from the same plate as Tom Stoppard. Also, the actors who performed joined in, so I also got to see Ralph Finnes, Simon R-B, Benedict Cumberbatch and probably some more, but my brain is still a bit fuzzy about the whole experience. the wine was free so I got pretty sloshed on top of all and barely manged to navigate my way back home...
