Jorah Mormont has spent the last six years of Game of Thrones wandering Essos in pursuit of the unrequited love-of-his-life Daenerys Targaryen.
Between Thrones and Jack Taylor, Glen has experience appearing in literary adaptations, although he acknowledges he doesn’t always physically resemble the characters as described in the books. As he tells it, that’s certainly the case with Jorah:
I don’t think I bear any physical resemblance whatsoever to the character that George R.R. Martin described in the books on which the series is based. I think he was a very dark-haired, wiry man with an ugly face–I’m not saying I don’t have an ugly face–and I think quite short and stocky […] But they probably thought it would be good if you could see why [Jorah and Daenerys] might get it together. If you had an ugly stump of a man who had no chance whatsoever and was fairly repellent then it would be harder for them to tell that story.
