Jane Austen Obsession and Fear of the Role
Knightley admitted that she literally grew up on Jane Austen's novel "Pride and Prejudice":According to Keira, she was so anxious about her role that before filming began, she memorized the script and even the lines of other actors by heart.I have been obsessed with this book since I was seven. When I was ten or eleven, I was obsessed with the BBC version. I finally read the book when I was about fourteen and became obsessed with it again. When I was offered this role, I was terrified of having to play it because I was truly obsessed with the role in the BBC series.
This dedication to the work and simultaneous fear of the iconic portrayal of Elizabeth by Jennifer Ehle (1995 series) made Keira approach the role with incredible responsibility.
