Dame Harriet Walter: English actress talks 'toughest role yet' in Brian and Maggie

Dame Harriet Walter's got plenty of memorable roles under her belt, from Succession, to Ted Lasso, to Killing Eve - and now she's taking on a part like no other. She portrays former UK Prime Minister Margaret Thatcher in the docuseries Brian and Maggie and she's opened up about taking on such a challenging role. "All actors like a challenge and this was a huge, huge mountain to get over. Among many reason was the fact that she's been played so often by brilliant actresses, so they've set the bar quite high."
