Mark Coulier, the prosthetic make-up designer on the film, explains that they used a surprisingly little amount of prosthetics whilst creating Margaret Thatcher.

Take a look at how they did it:

The movie follows an elderly Margaret Thatcher as she talks to the imagined presence of her recently deceased husband as she struggles to come to terms with his death while scenes from her past life, from girlhood to British prime minister, intervene.
