“Life Unexpected’s” Brittany Robertson is stepping into writer/producer Kevin Williamson’s new “Secret Circle.” Based on the book series from “Vampire Diaries” author L.J. Smith, the show stars Robertson as a California teen who discovers she’s a witch while living with her mother in New Salem.

Williamson, the creative force behind the Scream and I Know What You Did Last Summer films and the TV series “Dawson’s Creek” and “The Vampire Diaries,” is penning the pilot for The CW and will serve as executive producer. Cameras are expected to roll in Vancouver next month.

Robertson, who currently plays protagonist Lux Cassidy on The CW’s “Life Unexpected,” is coming off Wes Craven’s soon-to-be released Scream 4. The pretty 20-year-old’s only other horror cred is 2009’s supernatural teen thriller From Within.
