The Iron Lady

""Watch out, looking back. Don't dig too deep--you don't know what you might find...""

- Denis Thatcher's ghost, talking to Margaret

The Iron Lady is a 2011 Biopic about Margaret Thatcher starring Meryl Streep in an Oscar-winning performance as the eponymous character. The film uses the framework of Thatcher's dementia to look back on the fragments of her life through her increasingly-feeble grip on reality and memory.

Tropes:

 * Cloudcuckoolander: In her old age, Thatcher is getting a bit loopy. Mostly manifested through Denis (who, we should recall, is in Maggie's head).
 * Did Not Do the Research: Grantham, which is featured for less than five minutes, does not look like a Coronation Street set, and is not populated with people speaking with thick northern accents.
 * Fake Memories: It's implied that what we're seeing is somewhat coloured through Maggie's rosy lenses.
 * Foreshadowing:
 * Ghost Memory: Denis.
 * Imaginary Friend: In the present-day segments, Thatcher is accompanied by the delusory figure of her late husband. Jim Broadbent is clearly having the time of his life playing Denis.
 * Important Haircut: As part of Margaret's New Look.
 * Never Trust a Trailer: The fact that Thatcher even has dementia isn't even mentioned, despite being one of the film's most central themes.
 * Selective Memory: Maggie's are definitely slanted in her favor.
 * Unreliable Narrator: There are hints that the flashbacks are an example of this--the film (i.e. Thatcher) conveniently glosses over the negative aspects of her rule. And also, young Denis is a Hollywood heartthrob.
 * The Falklands War: Exactly what it says on the tin.
