It may be brief, but The Iron Lady teaser trailer is quite fun, just because it builds up the reveal of Meryl Streep as Margaret Thatcher as if this was the most amazing thing in the history of cinema. Perhaps if it had turned out it was Anna Faris playing Thatcher it would have been worth it, but the fact Streep has managed to transform herself both physically and vocally into someone else is pretty par for the course these day. The film follows the rise of Thatcher, with the makers promising a portrait of ‘a woman who smashed through the barriers of gender and class to be heard in a male-dominated world. The story concerns power and the price that is paid for power, and is a surprising and intimate portrait of an extraordinary and complex woman.’ Streep is Maggie, with Jim Broadbent as Denis, while Olivia Colman, Anthony Head, Richard E Grant, Angus Wright and John Sessions. The Iron Lady is due in UK cinemas January 6th, 2012, just in time for an Oscar run.
