That was over 37 years ago in 1984.
Today she is 75, and has starred in 115 movies in total, 84 since 2010 was released.
In 2010, I think Helen Mirren looks:
2010 scores 6.5 out of 10 on The Movie Database.
Helen Mirren's first acting role was as 'Advert Woman' in Herostratus, released in 1967 when she was 21.
