Finally, a detailed conclusion is made to show that the film is not only historically accurate, but also an important tool for teaching history in modern classes. Released in 2011, the film “The Iron Lady” revolves around the life and political career of Margaret Thatcher. The title “Iron Lady” is an adaptation of the nickname given to the former prime minister of Britain owing to her strong character, braveness and ability to trounce male political opponents 1 . The film was directed by Phyllida Lloyd, produced by Damian Jones and set in the UK and France. Much of the events are shown in a flashback style because the film is set in 2008 and attempts to show Thatcher’s life before, during and after her rule. The film begins by depicting the elderly Margaret Thatcher (Meryl Streep) buying milk from a local shop, with a number of other shoppers who seem not to recognize the former prime minister. She is shown walking back to her house alone, much like any other citizen. The film then concentrates on the life of Thatcher years after the end of her tenure. It provides evidence of her aging self, the effect of dementia and relationship with other people. She is depicted the woman who denies the death of her husband Dennis Thatcher. The film makes the audience realize that Thatcher’s memory is fast fading away due to age and dementia. It is evident that her personality is affected by her former role as a politician and the nation’s leader. For instance, she is unable to differentiate between the present and the past, which indicates that her memory is failing fast 2 . Yet, she seems to be neglected by her family, especially her son and daughter. The son, Mark Thatcher, lives away in South Africa, with little contact existing between him and the mother. In addition, her relationship with Carol Thatcher, her daughter, is sometimes strained, making her stay alone most of the times. The film then uses a flashback style to depict the previous life and career of the former Prime minister. The flashback begins with Lady Thatcher (Alexandra Roach) as a young girl in Grantham, where she is working in the family’s grocery store. The young woman seems interested in politics, especially her father’s political speeches. It is also evident that the relationship between the young Margaret and her mother is quite poor. The mother is a housewife, a lifestyle that seems less important to the young Thatcher. In addition, the film shows Margaret’s quest for education as it announces her successful application for Oxford University, one of the most prestigious institutions of higher education at the time. After her education, Margaret has to fight hard to break into the Tory Party and win a seat in the British House of Commons, especially because males dominate the party as well as other political fields 3 .
