Actress Bonnie Ferguson's expressions are very powerful - much harder to do in a film that has her completely mute. But in a way she speaks far louder than words ever could through her captivating facial expressions, physiognomy (it's a deafening silence) and compelling, quality acting. I'm sure a lot of the choices came from Alex Proyas' direction, but ultimately it falls on the actress to convince us...and for us to 'see' semblances of ourselves through and within her. An actress to watch out for, with a promising career.
