2015 is a busy year for Carter as she's also been cast as the Fairy God Mother in the live action Disney movie Cinderella. The Suffragette however, is based on the feminist movements of the late 19th Century and the early 20th Century focusing on the actions of Emmeline Pankhurst and fellow pioneers of equal rights for women. It also stars Meryl Streep so you know it's going to be good, and that the Oscars are likely to be sniffing around next year.
