The cast of "Game of Thrones" hit up the show's Hollywood premiere last night -- but you may not recognize most of them!

Though she plays the blonde Daenerys on the HBO show, Emilia Clarke looked like a completely different person on the red carpet. With dark brunette locks and a darker complexion, Clarke looked great -- and she's not the only one who got a major makeover.

Lena Headey also lost her blonde tresses for a dark black mane, while Maisie Williams and Gwendoline Christie -- who both sport more masculine looks on the show -- went girly and glam for the event.

Boys Kit Harington, Nikolaj Coster-Waldau, Peter Dinklage and Jason Momoa also cleaned up for the premiere, looking dapper as ever in suits on the red carpet.

See their transformations and more premiere pics in the gallery above -- and click here for a new trailer for the third season, which kicks off March 31.
