He spent 25 years as one of British television's most reliable prestige-drama faces without ever becoming properly famous. The Jewel in the Crown (1984) earned him a BAFTA nomination and a run of above-title bills in prestige films, and supporting roles in Alien 3 and Gosford Park kept him employed and respected. Then Game of Thrones happened. Benioff and Weiss cast him as Tywin Lannister after seeing him in Bleak House, and he appeared 27 times across four seasons, rarely raising his voice and never needing to.
The roles that defined him before Game of Thrones were supporting parts. The roles after are anchors. He played William Randolph Hearst in Mank (2020), appeared in The Crown, and landed the villain slot in The King's Man (2021). The First Omen (2024) put him in a priest's collar, and del Toro has him as Leopold Frankenstein in Frankenstein. Directors keep returning to him when they need men with authority and bad intentions. At nearly 80, he's more in demand as a lead than he was at 50.
His mother kept a secret from him his entire life: there were two half-sisters from his father's first marriage he never knew existed, and he and his brother Michael, ten years his senior, have different fathers. The BBC's Who Do You Think You Are? uncovered both, which is a lot of buried history for someone who plays men who know everything. Before acting, he was headed toward graphic design until two retired RADA actors took him under their wing. For someone who makes a career playing men with hidden agendas, the biographical concealment is almost on-brand.
