Having seen him in Sharpe I was a bit worried about him in Lord of the Rings.
However, he brought elements to Boromir that I hadn't seen in the book.
I realised with Sharpe that he's very much playing a character between two stools - raised from the ranks he is awkward with either group and this often shows by his good playing.
It's a fantastic portrayal of an officer up from the ranks! I study the Napoleonic Wars for my MA, my thesis is on the 95th Rifles so it's of particular interest to me! He wouldn't have been accepted properly by the officers and the men would often shun him for being made up. It's a lonely life.
Think he's pretty good in Game of Thrones, he's really great at the rugged personalities!
