First, Conan Stevens was interviewed over at The Tall Blog where he talks a lot about, as you might imagine, being tall. However he also has this to say about Thrones:
Working with HBO has been a good experience for me, mainly as I was working within the ‘Hollywood’ industry circles, rather than on the fringes. Pretty much everyone I was working with had a good track record and a ton of experience. For me to be chosen to work within these circles was a massive confirmation.
The other interview is with Aidan Gillen in the Irish Times. They talk mostly about his career and his role in the new Irish television drama Love/Hate, but touch briefly on Thrones:
He is distant. People know who he is, but he is hardly familiar. (“I’m Garbo-esque?” he smirks. But he doesn’t dispute that characterisation.) He has a dry sense of humour, compounded by a tendency to leer when it might be more profitable to smile. The facial hair he is sporting is for a role in the upcoming HBO series Game of Thrones (billed as “ The Sopranos in Middle Earth”), currently shooting in Belfast.
His character, Petyr Baelish, is a shadowy, mercurial figure. “So I based this look on Peter Mandelson circa 1984,” he says.
