We got lucky coming up the escalator because he was like three feet ahead of me, kathkin and Clarissa, and he was hanging round outside the screen with various people he clearly knew. Clarissa was like 'nooooo no i can't go up to him noooo' and I was like 'DO IT OR REGRET IT FOREVARRRR.' And then I grabbed her arm and towed her over to him and gave his arm a little nudge and introduced her.
It was WEIRDLY easy for me. Idk. I was a little bit jittery seeing him that close-to without the decorum-enforcing boundary of a signing table and security right there (BECAUSE HE'S MERLIN) but I had weirdly few hang-ups about striding up to him. I waited until he'd finished talking to his friends first and there was hardly anyone else around and he was just this very ordinary looking young guy in way-too-baggy-jeans, so it just felt kind of natural. Like making friendly chit-chat with a stranger outside a cinema like you would with anyone if you were waiting in a queue or something.
He asked where we were from and we told him Edinburgh/Canadia and then that we'd all read the book and he looked relieved and said 'oh so you know it's pretty dark then?' I think he was worried about traumatising poor innocent Merlin fangirls (and I was like 'OH COLIN. YOU HAVEN'T READ OUR FANFICTION.') There was like a few seconds when we were talking about how interesting the book was, then I told him we were sure he'd do it justice and he thanked us and then we went into the screen.
It was probably the best experience I've had with a cast member because it was so relaxed and easy. After the screening he was swamped by fangirls but by that point I was more interested in talking to the writer of the film, who was also there for the Q&A - this was her first big production and I quizzed her on her process and she was REALLY nice and told me to contact her on facebook if I had any more questions when we were finally ushered out of the cinema.
