Two-time Oscar winner Meryl Streep has been transformed for her role as former British Prime Minister Margaret Thatcher -- complete with the Iron Lady's trademark hairdo.
The Hollywood star is playing Thatcher in a biopic being made by 'Mamma Mia!' director Phyllida Lloyd.
Streep said: "The prospect of exploring the swathe cut through history by this remarkable woman is a daunting and exciting challenge.
"I am trying to approach the role with as much zeal, fervour and attention to detail as the real Lady Thatcher possesses."
The film, called 'The Iron Lady', also stars Jim Broadbent as her husband Denis. Other members of the cast include Anthony Head, Richard E Grant and John Sessions.
The film's publicists said it was the story of "a woman who smashed through the barriers of gender and class to be heard in a male-dominated world".
Filming began on location in the UK on January 31.
