Meryl Streep is said to be in final negotiations to join the cast of Suffragette.
The Iron Lady star would appear alongside Carey Mulligan in the historical drama about women in the early feminist movement, according to Screen International.
She would be set to play feminist trailblazer Emmeline Pankhurst, which would be a small but important role in the film and is said to include a "tour de force" speech on women's rights during a political rally.
Shooting on the film is set to begin in the UK and if Meryl agrees a deal, she will be reunited with her Iron Lady writer Abi Morgan and financier Pathe. Film4 and the BFI are also backing the project.
Carey will play Maude, a young feminist activist who turns to violence in a bid to push through changes to women's rights.
Meryl made headlines in January when she criticised Walt Disney and labelled him a "gender bigot".
She also received a record 18th Oscar nomination for Best Actress for her performance in August: Osage County, with the ceremony due to take place on March 2.
