On to Best Supporting Actress nominee Hailee Steinfeld for True Grit. To say this is a breakout performance is an understatement. Her portrayal of Mattie Ross is jaw-droppingly outstanding for such a young girl (she was 13 when she filmed True Grit). Plus, this is her first major acting gig! Mattie Ross is headstrong, and wise beyond her years as she takes it upon herself to find her father’s killer and avenge his death. She gets the help of US Deputy Marshal Rooster Cogburn in order to do this. Her character gets to the point of being almost annoying, however, this just shows how good she is as an actress (Steinfeld). She is a novice, but she manages to keep up with her more seasoned co-stars.
