Meryl Streep, reunited with Mamma Mia director Phyllida Lloyd, stars as Britain's first woman prime minister in this controversial imagined portrait. An aged Baroness Thatcher finds her memories - from her political beginnings to her 1980s heyday - beginning to blur as she suffers the effects of dementia. Streep's stunning impersonation won her Oscar and BAFTA awards for Best Actress in 2012.
