House of the Dragon's cast out of costume: Emma D'Arcy, Olivia Cooke, Matt Smith and more

Baela plays Daemon's eldest daughter in the hit show. A fearsome dragon rider - and betrothed to Rhaenyra's heir, Jacaerys, we're expecting great things from her! Bethany has previously starred in Stay Close and Russell T. Daves' ITV show, Nolly. 

They might not be a usurped Queen in real life, but Emma is definitely the Queen of serving incredible looks. The 32-year-old star is rocking a two-tone suit by Canaku for the HOTD premiere, a perfect look for when they’re not in their black and red gowns ready to wage war! 

Olivia, who is also known for starring in Bates Motel and Ready Player One, has a much more laid-back (and happier) vibe to her high-strung, miserable alter ego Queen Alicent Hightower. 

Matt is a natural brunette, and rocks the look in perhaps his best-known role as the Doctor in Doctor Who, but he is definitely not averse to going blonde! The actor dyed his hair to play Prince Philip in The Crown, and of course, donned a white-haired wig to play the anti-hero Daemon in the Game of Thrones spin-off. 

With his fake diamond eye, scar and long white-blonde locks, Ewan has a very memorable look in House of the Dragon, and we have to admit that we did a double-take seeing what he looks like out of his blonde wig!

Although Ser Cristen is, quite simply, the worst, we can’t deny that he looks good in his Kingsguard suit - almost as good as Fabien does in a suit at the House of the Dragon premiere in real life!

We would never have recognised Alicent’s only daughter Halaena if actress Phia Saban walked past us in the street. We have to say though, we love her red carpet look. 

The Red, White and Blue star is unrecognisable as the power-hungry sailor in House of the Dragon - even though we also think that Coryls character would suit a pair of shades. 

You might recognise Freddie from shows including White House Farm and Slow Horses, but he has again transformed for this period drama role as Alicent’s brother. Although we haven’t seen a lot of Gwayne just yet - we expect he’ll be an important player in the dance of the dragons.
