Casualty 40th Anniversary Special to Feature Return of Charlie and Ethan

The BBC's long-running medical drama Casualty is set to celebrate its 40th anniversary with a special double-bill episode on Saturday, September 5, 2026, featuring the return of two of its most iconic characters. Derek Thompson will reprise his role as senior charge nurse Charlie Fairhead, and George Rainsford will return as doctor Ethan Hardy for the milestone event. The anniversary episodes will centre on a high-stakes major incident that throws the fictional Holby City Hospital into chaos. According to the official synopsis, lives hang in the balance as the emergency department team is pushed to their limits in a tense and emotionally charged story. As the fallout continues, a major rescue operation unfolds, forcing impossible life-or-death decisions and testing the courage, resilience, and leadership of the hospital staff. Thompson's return marks his first appearance as Charlie since departing the series in 2024. The character, who was in the show's very first episode in 1986, retired after being stabbed by a patient attempting to steal medical supplies. Thompson portrayed the senior nurse for 38 years across nearly 900 episodes.
