For millions of viewers around the world, Emilia Clarke became synonymous with strength through her portrayal of Daenerys Targaryen in the global hit series Game of Thrones. On screen, she commanded armies, faced dragons, and inspired loyalty from millions of fans. But behind the scenes, Clarke was quietly fighting a far more terrifying battle—one that nearly cost her life.
Actor Jason Momoa, who portrayed Khal Drogo in the early seasons of the show, later reflected on the emotional shock of learning just how serious Clarke’s health crisis had been. During the early years of the series, Clarke suffered two life-threatening brain aneurysms, medical emergencies that required multiple surgeries and a long, painful recovery.
The first aneurysm occurred in 2011, shortly after the first season of Game of Thrones finished filming. Clarke suddenly experienced a severe headache during a workout, later collapsing and being rushed to the hospital. Doctors diagnosed her with a type of stroke known as a subarachnoid hemorrhage, caused by a ruptured brain aneurysm. Emergency surgery followed, beginning a frightening medical ordeal that few people in the industry even knew was happening.
For Momoa and others close to Clarke, the experience was deeply unsettling. The actress was still early in her career, and the massive success of Game of Thrones had just begun to reshape the television landscape. The thought that the young star behind such an iconic character might not survive was almost unimaginable.
Clarke endured intense pain and uncertainty during her recovery, at times struggling with memory and speech as her brain healed. Despite those challenges, she was determined to return to work. Not long after her first surgery, she was back filming scenes as Daenerys, performing under immense pressure while privately managing the lingering effects of her condition.
Just as she was beginning to regain stability, Clarke faced another terrifying setback. In 2013, doctors discovered a second aneurysm that required an additional operation. The procedure was even more complex and carried serious risks, leaving Clarke once again fighting for her health and cognitive function.
Momoa later expressed amazement at the resilience she displayed during that time. While audiences saw a fearless queen on television, Clarke was quietly navigating hospital visits, recovery periods, and the constant fear of another medical emergency. To many of her colleagues, the realization that she had endured so much without public complaint was both shocking and inspiring.
For Momoa, the situation highlighted just how fragile life can be—even in the glamorous world of entertainment. He spoke about the helplessness he felt watching a close friend face such danger and the overwhelming relief that followed when she pulled through.
Years later, Clarke chose to share her story publicly, helping raise awareness about brain injuries and recovery. She even helped establish charitable efforts supporting neurological rehabilitation, turning her own frightening experience into an opportunity to help others.
Looking back, the ordeal revealed a side of Clarke that fans rarely saw: not just the powerful “Mother of Dragons,” but a woman who fought quietly and courageously for her own survival. For Momoa and millions of viewers, the knowledge of what she endured behind the scenes only deepened the admiration for the strength she carried both on and off the screen.
