Meryl Streep, Helena Bonham Carter, Carey Mulligan and Anne Marie Duff have joined relatives of Suffragette leader Emmeline Pankhurst to mark this year’s International Women’s Day. The three actresses were joined by Pankhurst’s great-grand-daughter Helen and great-great-granddaughter Laura as well as director Sarah Gavron, screenwriter Abi Morgan and producers Alison Owen and Faye Ward who are behind the upcoming Suffragette movie.

The photograph, taken by Brigitte Lacombe is the first time the stars of the upcoming movie have posed together. In the film, Oscar winner Streep stars as political activist Pankhurst who paved the way for women to get the vote in Britain and led support for the war effort during the First World War.

Speaking about Pankhurst and the Suffragette movement Streep commented, “Every daughter should know this history, every son write it on his own heart." The actress along with her co-stars have been spotted around London filming for the movie in famous locations such as Holloway Prison and The Houses of Parliament, which was the scene of a grand protest in 1908.

The movie is the first commercial film in history to be allowed to use The Houses of Parliament as a location, something which director Sarah Gavron is very grateful for. “Our film is inspired by the true stories of the foot soldiers of the Suffragette movement, women who were willing to sacrifice everything in their fight for the right to vote,” Gavron told the BBC.
