Pennywise - It (1990)

Long before modern big-screen remakes, Curry single-handedly terrorised television audiences in the 1990 two-part TV adaptation of Stephen King's horror masterpiece. He balanced twisted, carnival humour with genuine, unadulterated malice, making Pennywise an unforgettable pop-culture nightmare. His performance was famously so unsettling that his fellow cast members actively avoided him on set between takes. This chilling portrayal translated into a massive ratings triumph for ABC, drawing over 30 million viewers during its two-night premiere. The production is widely credited with reviving the horror miniseries format on mainstream television, and Curry's terrifying work laid the foundational groundwork for the billion-dollar movie franchise that followed decades later.
