ER and George Clooney: Context for the Departure
George Clooney joined ER in 1994 as Dr. Doug Ross, an attending pediatric emergency medicine fellow known for his charisma and rule‑pushing brilliance. His tenure occurred during the show’s formative years, establishing many of the serialized character dynamics that fueled its early success.
