We already learned about Margaret Thatcher’s non-negotiable pearls and got a good look at her in previous promotional materials for The Iron Lady. Now, a new U.K. trailer has been released for Meryl Streep’s upcoming Thatcher biopic. Underscored by Madness’s “Our House,” the trailer showcases the femininity that made Thatcher a standout politician (can you imagine Pierre Trudeau or Mikhail Gorbachev going for a spin on the dance floor with Ronald Reagan?) and conveys the conflict that arose from Thatcher’s dogged drive — the very same drive that led her to make history by becoming the U.K’s first female prime minister. Thatcher certainly owns the first half of the trailer, but Streep is the star of the second, as her sure-to-be-Oscar-nominated performance walks a tightrope between Thatcher’s tough-as-nails political persona and her personal vulnerability. See the full trailer after the jump.

Streep re-teamed with Mamma Mia! helmer Phyllida Lloyd for The Iron Lady, which also stars Jim Broadbent, Anthony Head, and Richard E. Grant. The film opens Dec. 16.
