Margaret Thatcher will be portrayed by Meryl Streep in this upcoming biopic slated for theatrical release this December; Thatcher's enormously strong-willed foreign policy and the price she's had to pay for her outsized posturing will form the underpinnings of this day-in-the-life-styled film. Thatcher, who is still alive, suffers from Alzheimers disease and has retired from public life. Other cast members include Jim Broadbent playing Denis Thatcher, the iron lady's husband.
