"Terminator: The Sarah Connor Chronicles" star Thomas Dekker will play the male lead in "The Secret Circle," The CW's pilot based on author L.J. Smith's witch tale, according to Deadline.

Kevin Williamson ("Scream"), co-creator and executive producer of "The Vampire Diaries," is co-writing the pilot with Andrew Miller. They will executive produce the project along with Elizabeth Craft, Sarah Fain, Leslie Morgenstein and Gina Girolamo.

"The Secret Circle" follows a shy teenage girl, played by Britt Robertson ("Life Unexpected"), who moves to a new town and who learns that she is a witch. As a member of a secret coven, she soon becomes the key that will unlock an ancient battle between good and evil.

Dekker will play a member of the witches' circle.

Produced by the studios behind "The Vampire Diaries" -- Alloy Entertainment, WBTV and CBS TV Studios -- the pilot joins five other projects previously picked up by The CW. Two of the pilots are also genre shows: "Awakening," a zombie drama, and "Heavenly," a legal drama with supernatural elements.

Williamson has enjoyed a healthy workload recently. In addition to spearheading the hit series "The Vampire Diaries," his film "Scream 4," directed by Wes Craven ("A Nightmare on Elm Street"), hits theaters April 15. He is also penning "The Bedroom Window," based on the novel "The Witnesses" by Anne Holden.
