Lord Eddard Stark (Sean Bean)
Does the Lord of the Rings vet just really like costume dramas? Says Bean: ''They like me. I'm getting used to these kind-of medieval themes. I do enjoy doing period pieces and historical pieces in general. They usually look good and you feel good in them.''

Queen Cersei (Lena Headey)
Headey on transitioning from more action-oriented roles such as The Sarah Connor Chronicles: ''I was such a dude [in previous series]. My husband's always like, 'You look great in a dress!' And I try, I do. But this is very girly. I f---ing hate hair and makeup.''

Lady Catelynn Stark (Michelle Fairley)
Fairley on her stately gowns: ''It gives you a sense of stature. We haven't got corsets, but you still stand differently. It's another wonderful layer [of character] to be added on.''

King Robert Baratheon (Mark Addy)
''This is all fake,'' Addy says after getting his beard reglued by makeup artists on the Belfast set. ''The fussing is annoying, but it's a necessary part of it. The bizarre thing is that at the end of the day, people get so used to seeing you with all of this on that they don't recognize you without it. It's a cunning disguise.''

Khal Drogo (Jason Momoa)
Momoa on getting into character: ''I look in the mirror, and I don't have to do anything. I just look f---ing scary. That's one of the things with this, the wardrobe and makeup. It's fantastic.''

Tyrion Lannister (Peter Dinklage)
''In The Chronicles of Narnia, I had chainmail. What's nice about this role is I don't have to do too much of that. He's not a warrior. He's mainly in nightgowns. He spends a lot of time in the brothel. It's rare that my character has to pick up a sword,'' says Dinklage.

Daenerys Targaryen (Emilia Clarke)
''I love the hair. I absolutely love it. When they first put me in the wig, I went, 'I want to go blond, that's it.' It's so cool to be able to have costumes so completely different from yourself,'' says Clarke.
