This was the first film that was allowed to be shot in the British Houses of Parliament since the 1950s.
Helena Bonham Carter is the great-granddaughter of H.H. Asquith, who served as the Prime Minister of the United Kingdom from 1908 to 1916, during the height of the suffrage movement. He was a staunch opponent of votes for women.
Helen Pankhurst, the great-granddaughter of Emmeline Pankhurst, and her daughter Laura have small roles in the film.
At the London premiere, feminist direct action group Sisters Uncut jumped the barriers and staged a lie-in on the red carpet to protest against cuts to domestic violence services, declaring "the battle isn't over yet". The stars of the film continued giving interviews and meeting fans as the activists chanted "Dead women can't vote" and "We are suffragettes". Interviewed at the premiere, Helena Bonham Carter said: "I'm glad our film has done something. That's exactly what it's there for," adding that the protest was the "perfect" response to the film.
Carey Mulligan didn't wash her hair for weeks during the shoot and wore very little make up to give her character a real feel.
