It's your first look at Carey Mulligan in Suffragette! Mulligan was snapped filming at Parliament on April 11, 2014 in London, England. Suffragette, which stars Mulligan, Helena Bonham Carter and Meryl Streep as the foot soldiers of the early feminist movement, is the first film to be allowed to shoot in the Houses of Parliament. Suffragette is scheduled to be released in 2015.
The foot soldiers of the early feminist movement, women who were forced underground to pursue a dangerous game of cat and mouse with an increasingly brutal State.
