In my 11.23 Iron Lady review I included an impression that “at least 45% [is] about octagenerian Maggie (superbly played by Streep and assisted by a first-rate makeup job), 45% about Maggie in her political prime (Streep again, guns blazing) and 10% about very young Maggie (Alexandra Roach) and young Denis Thatcher (Harry Lloyd).”

It turns out I was wrong, especially on my old Maggie estimate. A few hours after my review appeared a publicist for the film said she’d asked the filmmakers for a precise mathematical breakdown and got this answer: “60% of The Iron Lady is about Maggie in her political prime, 15% focuses on young Maggie, and 25% on old Maggie. I hope that’s helpful.”
