Olivia Cooke Dazzles in Princess Gown at Premiere

Olivia Cooke dressed to impress in a bold white strapless princess gown as she attended the series three world premiere in London on Monday.

The actress, 32, turned heads in the dramatic number as she joined leading man Matt Smith on the star-studded red carpet held at Odeon West End.

Olivia, who plays Queen Alicent Hightower in the hit series, looked incredible in the strapless corset style ensemble which boasted buttons up the front and a huge layered pleated skirt. 

Styling her dark tresses in loose waves, the British star simply accessorised with silver and green dazzling earrings and a matching chunky ring. 

Meanwhile Matt, 43, who portrays lead role Daemon Targaryen in the HBO series, was all smiles as he hit the red carpet in a dapper black suit.

The actor dressed smart in the three-piece suit which he teamed with a cool pair of sunglasses. 

Elsewhere Emma D’Arcy looked effortlessly cool as they tucked a grey shirt into smart pleased trousers. 

The star, who plays Princess Rhaenyra Targaryen, slung a coordinated blazer over their shoulder and accessorised with sunglasses and silver necklaces. 

The premiere comes days after co-creator Ryan Condal declared, 'These sequences, I will confidently say, are unlike anything that's ever been done on television before.'

Ryan joined the panel at SXSW London where he insisted House of the Dragon will be bigger than ever.

The fantasy series House of the Dragon is returning for an eight-episode third season which will launch from June 22 on HBO Max, with further episodes airing weekly until the finale on August 10. 

Book readers will know immediately that he's referring to The Battle of the Gullet, an epic and gruesomely bloody clash that takes place across land and sea and is the defining centerpiece of Targaryen civil war in House of the Dragon that predates the events of The Game of Thrones by about 200 years. 

The entire series has been leading up to this moment, which even fictional historians would deem to be the bloodiest naval battle in Westerosi history.

'The amount of construction that you guys did for just the one episode is kind of crazy and frankly irresponsible,' Ryan teased. 'But it was necessary to tell the story, and this is such a seminal moment for the show.'

The conflict was originally sparked by a fatal misunderstanding at the end of season one, when the dying King Viserys (Paddy Considine) whispers a prophecy about 'Aegon the Conqueror' to Queen Alicent (Olivia Cooke). 

Alicent mistakenly thinks her husband has ordered their son Aegon II (Tom Glynn-Carney) to become king instead of his chosen heir, Rhaenyra (Emma D'Arcy). 

As Alicent and her cohort crown King Aegon II and shut down the Red Keep, Rhaenyra takes off on her dragon to go on the attack. 

Season two ended as family tensions turned into a full-scale civil war and season three will pick up seconds after that. 

The prequel to smash-hit , hit screens back in 2022 and dropped it's series three trailor back in April. 

Major cast members including , Emma D'Arcy, Olivia Cooke, Steve Toussaint, Rhys Ifans and will be back for season three.

Also appearing are Ewan Mitchell, Tom Glynn-Carney, Sonoya Mizuno, Harry Collett, Bethany Antonia, Phoebe Campbell, Phia Saban, Jefferson Hall, Matthew Needham, and .

Previously, fans shared their excitement as a very violent season three trailer dropped - with warring soldiers butchered and burned alive.

Writing in the comments section, one fan penned: 'Now we are talking; This season is dark and full of terrors; My boy, Daemon finally getting the Action he deserves!!

'This series is so dark, so tragic and epic...pure gold; This looks better than season 2. Let's hope it delivers.'

Elsewhere, viewers of were left devastated by a heartbreaking death.

Set a century before Game of Thrones, A Knight Of The Seven Kingdoms follows a lowborn knight named Dunk (Peter Claffey) and his squire Egg (Dexter Sol Ansell). 

Titled In the Name of the Mother, the storyline featured the dreaded Trial of the Seven.

Prince Baelor 'Breakspear' Targaryen (Bertie Carvel) aligned with main character Dunk's team - in an unexpected move.

This was an attempt to protect his brother and nephews, who were on the opposing side.

Although an honourable decision, Baelor unfortunately met a tragic end in the episode.

Baelor's skull was crushed by a mace belonging to his brother Maekar (Sam Spruell) and he succumbed to these wounds.

Writing on X, viewers penned: 'Baelor Targaryen you will be missed by all; Baelor take me with you; All of us at Baelor's funeral; 

'Just want to give a huge round of applause to Bertie Carvel for his performance as Baelor Targaryen. He really brought to life one of the best Asoiaf characters.'

Speaking to Entertainment Weekly, showrunner Ira Parker said of Baelor: 'At so young in his life, he became this war hero, this savior of the kingdom and the realm.

'Because of his nature, everybody's telling him how honorable he is and how he's gonna make the greatest king that Westeros has ever had since the Conqueror. 

'And then finally a moment comes for him to actually put up when his honor is tested in truth. Virtue untested is no virtue at all.'
