It’s Emmy season, so we’ve got another episode of the “Envelope” for you. This time, it’s an in-depth conversation with Gillian Anderson, who plays Eleanor Roosevelt in “The First Lady.” Anderson talks about how Eleanor Roosevelt was the brains behind the FDR presidency, the focus on Roosevelt’s loving relationship with journalist Lorena Hickok in “The First Lady,” and why it took her some time to click with “Sex Education.” Taking on a historical figure isn’t new for Anderson — who also plays Margaret Thatcher in “The Crown” and Catherine’s mother, Joanna, in “The Great.” Nor is portraying a character who stays in her lane, which wasn’t a stretch from Anderson’s own personality.
