That was over 15 years ago in 2007.
Today she is 28, and has starred in 26 movies in total, 23 since Atonement was released.
In Atonement, I think Saoirse Ronan looks:
Atonement scores 7.5 out of 10 on The Movie Database.
Saoirse Ronan's first acting role was as 'Briony Tallis (Age 13)' in Atonement, released in 2007 when she was 13.
