Before stepping into one of the most unforgettable roles in the history of TV police dramas, James MacArthur was a young actor with a boyish charm. Best known as Danny “Danno” Williams from the long-running series “Hawaii Five-O,” which aired on CBS from 1968 to 1980, MacArthur became a household name over the show’s 11 seasons. His famous line, “Book ‘em, Danno,” would go on to become a cultural touchstone.
Born the adopted son of celebrated actress Helen Hayes, James began his career in the spotlight by acting alongside her on radio. That early exposure paved the way for his eventual rise in Hollywood. He later became the youthful face of several live-action adventure films produced by Walt Disney Pictures, among them the 1961 hit “Swiss Family Robinson.”
Throughout his early years in the entertainment industry, MacArthur appeared regularly in both film and television, often in guest roles or supporting parts. These roles helped build his presence in the industry until he landed the part that would define his career on “Hawaii Five-O.” That role kept him in the public eye for more than a decade.
Though he never quite reached the same level of fame after leaving the show, MacArthur’s contributions to television and film left a lasting impression. His body of work, especially his time on “Hawaii Five-O,” ensured that his name would be remembered by fans and critics alike.
When it comes to James MacArthur’s career highlights, one film that really stands out is Hang ‘Em High from 1968—it’s widely regarded as James MacArthur’s highest rated movie. Critics and fans alike have praised the film over the years, giving it strong marks for its storytelling and performances. On the other end of the spectrum, James MacArthur appeared in The Interns back in 1962, a film that, while notable for being an early role, ended up being his lowest rated movie. Though James MacArthur brought solid effort to the project, the overall reception wasn’t as favorable. Still, looking at James MacArthur’s filmography, it’s clear he had a range—from standout Westerns to ensemble medical dramas—showing his versatility as an actor.
