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.

Helen Pankhurst, the great-granddaughter of Emmeline Pankhurst (Meryl Streep in 'Suffragette'), and her daughter Laura have small roles in the film.

Although they did not share any scenes Brendan Gleeson and Meryl Streep previously acted in "Artificial Intelligence". Brendan Gleeson is also due to act in Ron Howard's "In the heart of the sea" with Ben Whishaw. He also played Mad Eye Moody in the Harry Potter franchise with Helena Bonham Carter.
