Even if you haven't been watching MASTERPIECE every Sunday for the past 50 years, there's a very good chance you tuned in to watch Downton Abbey. The six-season epic brought renewed attention to the drama anthology series when it first aired more than a decade ago, and we look back at the interconnected lives of the Crawley clan and their servants with a few of the people who helped the title turn heads and claim awards. And in this final episode of our three-part docuseries, we explore how MASTERPIECE might continue to evolve for the next 50 years, tackling the challenges and opportunities still ahead.

We speak with Julian Fellowes, Hugh Bonneville, Elizabeth McGovern, Lily Collins and more. See our website, pbs.org/makingmasterpiece for a detailed transcript, complete with references and links.
