I do not regret having done 'Game of Thrones,' but I have nothing to say. I understood neither the series nor its success when I was attending. The experience was very strange; it passed under my nose.
If you feel uncomfortable on stage, you can very easily descend into a sort of abyss, convinced you're the worst actor ever, that you're a disgrace to the profession, that you're a disgrace to yourself. It's an awful feeling.
