There is no greater symbol of the artistic spirit of Scotland than the Mackintosh building. But more than that it is a symbol of where art belongs, rising as it does out of the heart of a great city. A mighty castle on a hill, it is a part of me, and of all Glaswegians.

I think acting, oftentimes it's not about lines, it's about spaces in between lines and expressions on people's faces and their relationships. You can tell your own story, or a story that you're interested in, even if the lines don't necessarily point you in that direction.
