Movies I'm Looking Forward to Watch: The Iron Lady

I grew up with a Britain being ruled by Margaret Thatcher. I have no idea as to how British politics works but this woman really showed a lot of guts bringing Britain into the Falklands War in the early 80s and the fact that she was a woman running a First World country - or any country for that matter - was already a very interesting fact. Of course they had get Meryl Streep to play this role. Who else can be 'The Iron Lady'?
