"Game of Thrones" comes back in the shape of the prequel "House of the Dragon," which premiered in Los Angeles on Wednesday night with an all-new cast.

Ryan Condal and Miguel Sapochnik are the new showrunners, having succeeded David Benioff and D.B. Weiss.

"There is more prosperity, there has been a half century of peace, but this is mostly a story about a divided house. It's about a solitary house falling apart from the inside out," explained Condal.

The show begins with Paddy Considine's King Viserys Targaryen deciding between his brother Prince Daemon (Matt Smith) and his daughter Princess Rhaenyra (Emma D'Arcy) as his next heir.

Nonetheless, a third contender for the crown emerges. Olivia Cooke portrays Alicent Hightower, the lifelong best friend of Princess Rhaenyra, who marries the king after his first wife dies in childbirth.

Cooke stated that she loved the trailer's depictions of her and D'Arcy in tense situations. "For me, acting alongside Emma is like sparring with Mike Tyson (the boxer). I adore them so much, despite the fact that we appear to dislike one other on-screen."

This is D'Arcy's most significant part to date, and she is preparing for instant fame.

"I'm thrilled that the play will have an audience. I can't say what that means for me in my day-to-day life, but I'm curious to see what others make of it "D'Arcy remarked.

Rhys Ifans, who portrays Alicent's father, Ser Otto Hightower, and is also the Hand of the King, expressed optimism about the show's future.

It remains to be seen if it resonates with millions of followers and new viewers.

On August 21, "House of the Dragon" began streaming on HBO.
