James MacArthur, celebrated for his role as Detective Danny "Danno" Williams on the iconic crime drama Hawaii Five-O, had a notable career that spanned decades.

Beyond his on-screen presence, MacArthur hailed from a distinguished Hollywood family. He was the adopted son of Helen Hayes, the "First Lady of American Theatre" and the first woman to achieve EGOT status, and Charles MacArthur, an Academy Award-winning writer. This artistic lineage undoubtedly influenced his path in the entertainment industry.
