I remember my first scene with Alan Rickman, and I was anxious because he is a slight 'method' actor; as soon as he is in his cloak, he walks and talks like Snape - it is quite terrifying. But I really wanted to talk to him because 'Robin Hood' was one of my favourite films.

I already love the idea that Barry has a colleague. It seems like a love/hate thing between my character and his already.
