That's awesome! Congrats!
I went to see
Ivanov the other day (it was AMAZING, by the way) and got to meet Andrea Riseborough, Kevin R McNally and Malcolm Sinclair at the stagedoor. Which is great because they were my favourites in the play =) I had already meet Andrea the day before doing a reading at the Royal Court (I'm a HUGE fan of hers, she's amazing) and she's absolutely lovely.
It's great that you met Kenneth Branagh! He was very good in the play and I'd love to ask him to sign my programme, but I don't really like waiting before performances... so I don't know. I'm really gonna try to see the play again anyway. Andrea told us to go say 'hi' to her again if we came back =D
The Female of the Species was quite nice. I went to see it in July and got my programme signed by Eileen Atkins (who was really nice) and Anna Maxwell Martin (who was in a hurry but waited a bit for us anyway). You're so lucky Phyllida Law was at the stagedoor too!
Oh, and I got to see
Riflemind in the end. I didn't really like the play, but John Hannah was
amazing in it and he was lovely to us later. He was relly very nice, as you said =D
