Actress Erin Moriarty has shared details about the difficult health challenges she experienced while filming the final season of The Boys, revealing how an undiagnosed illness affected both her personal life and work on the series.
Actress Recalls Difficult Period During Filming
Erin Moriarty, known for portraying Annie January (Starlight) in the hit series The Boys, discussed her experience dealing with chronic illness while filming the show’s final season.
In a personal essay, Moriarty described the period as an extremely difficult chapter in her life, explaining that before receiving a diagnosis she experienced severe physical symptoms that significantly affected her day-to-day functioning.
She recalled feeling physically exhausted and emotionally overwhelmed, saying the uncertainty surrounding her health created fear and confusion.
Impact on Her Work and Personal Identity
Moriarty explained that the symptoms began affecting her connection with the character she had played for years. According to her account, the illness created a sense of distance between herself and the role that had become an important part of her life.
She stated that memory difficulties and physical discomfort made the filming process increasingly challenging. The actress also shared that experiencing these struggles publicly added another layer of emotional stress.
She wrote that dealing with health issues privately is already difficult, but having visible symptoms become the subject of public speculation made the situation more painful.
Diagnosis of Graves’ Disease
In June 2025, Moriarty publicly revealed that she had been diagnosed with Graves’ disease.
Graves’ disease is an autoimmune disorder that affects the thyroid gland. It occurs when the immune system mistakenly attacks the thyroid, causing it to become overactive.
Understanding Graves’ Disease
The condition can affect multiple systems within the body and may cause a variety of symptoms, including:
- Unexplained weight loss
- Sensitivity to heat
- Tremors or shaking
- Rapid or irregular heartbeat
- Fatigue and weakness
- Anxiety and mood changes
Some individuals may also develop Graves’ ophthalmopathy, a condition that can affect the eyes and lead to symptoms such as:
- Eye irritation or pressure
- Increased sensitivity to light
- Bulging eyes
- Vision-related discomfort
Symptoms and severity can vary significantly from one person to another.
Moving Forward After Diagnosis
Moriarty’s comments provide insight into the challenges that can accompany chronic illnesses, particularly when symptoms remain undiagnosed for extended periods.
As The Boys approaches its conclusion, her reflections have also given fans a deeper understanding of the personal struggles she faced while continuing to work throughout the series’ final chapter.
