Co-stars Olivia Cooke and Emma D'Arcy shared a warm, candid moment on the red carpet at the 'House of the Dragon Season 3' world premiere, held at the Odeon West End in London on June 8, 2026. Showing off a playful and supportive dynamic that contrasts beautifully with their fierce on-screen rivalry as Queen Alicent Hightower and Queen Rhaenyra Targaryen, the duo brought plenty of poise and style to the London crowd. The star-studded event officially kicks off the countdown to Season 3, which is scheduled to premiere on June 21, 2026, on HBO and Max.
