Exclusive: The Iron Lady Featurette

Behind the scenes on 'Maggie The Movie'

Making a biopic (of sorts) about a person as divisive as Margaret Thatcher is no mean feat.

A tip of the cap then to Mamma Mia director Phyllida Lloyd for bringing us The Iron Lady, with Meryl "I'll have an Oscar with that" Streep playing Maggie herself.

To show a little bit more about how it was done, here's a featurette that shows a few things from behind the scenes, from thre Parliament scenes to, well, you'll have to find out for yourself really.

In other words, if you're a die-hard Thatcher-loather, you may want to click away now. But if you're interested in an upcoming film about Britain's first female Prime Minister, then this'll be right up your alley.

The Iron Lady is out in cinemas on January 6.
