The Charlie & The Chocolate Factory star nearly missed out on playing a young Carrie Bradshaw because she didn't want to be tied down to a long-running show.
However, the 19-year-old actress decided to sign up for the The Carrie Diaries after reading the script for the project, which is set in a high school in the 1980s.
She tells Teen Vogue magazine, "When I was younger, I didn't want to be on Tv. I made a conscious decision to stay away from Nickelodeon and the Disney Channel - not that they're not great companies, but because I wanted to play different kinds of roles and have the freedom to choose my projects.
"So when my agent called about this job, I said no way. Tv was too much of a commitment. I realised it was actually a really strong story. It had a lot of heart and integrity, and Carrie seems like a character that I can grow with."
Sarah Jessica Parker made the role of Bradshaw famous in the Sex & The City franchise.
