Celia Imrie tells the story of Glenda Jackson, one of Britain's greatest-ever acting talents and a double Oscar winner, who famously turned her back on her hugely successful screen career to pursue a life in politics. With interviews and rarely seen moments from the BBC's archives, this programme explores Jackson's career to gain insight into the choices and aspirations that drove her over the years. There's also a look at how those famous appearances alongside Morecambe and Wise showed that a world-renowned star, known for her serious roles and strong principles, was still capable of having fun and celebrating the ridiculous side of life.
