--> [[ImaginaryFriend Denis Thatcher's ghost]], talking to Margaret

''The Iron Lady'' is a 2011 {{Biopic}} about MargaretThatcher starring Creator/MerylStreep 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:
* DeathGlare: Thatcher gives an undeserved one to her cabinet just because some ministers are beginning to disagree with her on certain policies
* IronLady: [[ShapedLikeItself You Don't Say]]! Even as an old senile woman, talking in private to her doctor, she gives detached speeches about how people spend too much time on their feelings instead of their thoughts.
* CloudCuckooLander: In her old age, Thatcher is getting a bit loopy. Mostly manifested through Denis (who, we should recall, is in ''Maggie's'' head).
* CommanderContrarian: Thatcher shoots down ''any'' criticism to her policies from her opponnets and fellow Tories. It eventually backfires after her cabinet just can't take it any more.
* FatalFlaw: Well to her political career anyway, Maggie's flaw is that she believes herself to be right about everyone, and her ministers aren't. Eventually her cabinet gets fed up with this, which leads to her losing the Premiership
* FakeMemories: It's implied that what we're seeing is somewhat coloured through Maggie's rosy lenses.
* {{Foreshadowing}}: [[spoiler:In the scene where Denis proposes to Margaret, she exclaims, "I donʻt want to end life washing up a teacup!" Sheʻs doing exactly that in the movieʻs final scene.]]
** Roughly halfway, Geoffrey Howe warns Maggie that she shouldn't test her collauges loyalty too far. Eventually after a particularly vicious ReasonYouSuckSpeech, Howe resigns which sets off a chain of events that lead to Thatcher's resignation as Prime Minister rather be humiliated by loosing our election.
* GhostMemory: Denis.
* HistoricalHeroUpgrade: The damage Thatcher did to industrial communities is skated over, with the protesters being shown in a fairly unsympathetic light, whilst Michael Foot is supposedly a buffoon. The film, regardless of artistic quality, is shameless hagiography from beginning to end.
* ImaginaryFriend: In the present-day segments, Thatcher is accompanied by the illusory figure of her late husband. JimBroadbent is clearly having the time of his life playing Denis.
* ImportantHaircut: As part of Margaret's New Look.
* NeverTrustATrailer: The fact that Thatcher even ''has'' dementia isn't even mentioned, despite being one of the film's most central themes.
* RantInducingSlight/ ReasonYouSuckSpeech: Thatcher gives a rather malicious one to her ''entire'' cabinet, just because they correctly believe that her proposed "Community Charge" is considered unfair by most people and it would be a good idea to drop it, and tell her so to her face.
* SelectiveMemory: Maggie's are definitely slanted in her favor.
* UndyingLoyalty: Averted. Howe warns Maggie that she must not test the loyalty of her collauges too far. Maggie doesn't listen and eventually her cabinet turns on her after being humilitated and having their concerns and opinions shut down once too often.
* UnreliableNarrator: 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.
* TheUnseen: Mark Thatcher.
* UsefulNotes/TheFalklandsWar: Exactly what it says on the tin.
* YouAreWhatYouHate: As a young PM, Maggie was frustrated that her opinions and concerns were always shot down by others.....so when she becomes Prime Minister she does the same not only to the Labour Oppostion but also her own cabinent. It doesn't end well for her.
