Matt Smith of House of the Dragon says his character is "as an outsider." ...

Matt Smith, who plays Daemon Targaryen in House of the Dragon, has spoken up about his character, a "grumpy" and "volatile" prince.

The Game of Thrones prequel on HBO chronicles the demise of a dragon-riding dynasty, with Paddy Considine topping the table as Daemon's king brother Viserys.

Smith told Rolling Stone that he is a sort of an outsider. He isn't black and white, there are shades of grey with him, which is what interested me about him. And his friendship with his brother is really interesting."

The former Doctor isn't in any hurry to wear that wig again when it comes to those platinum locks.

"It's a f**king pain in the arse," he said. "It took an hour and a quarter to put on every day." I was like, 'Of course the Targaryens are famous for their blonde hair, but can't we just give them some highlights?'

Daemon is considered a fierce warrior and accomplished dragon flight by author George RR Martin.

"My dragon is Caraxes," said Smith. "He's a bit of a Daemon incarnation; he's grumpy, sardonic, insular, volatile, and clumsy.

"There's a very strong connection between the dragon and the dragonrider."

"There's an actual dragon, and you sit on it and they move it around by remote control, while shooting rain and all kinds of things at you," Smith continued.

Seasons 1-8 of Game of Thrones are now available on DVD and Blu-ray. House of the Dragon, the spin-off series, will premiere on August 21 in the United Kingdom.
