'The Secret Circle' casting news: A 'Queer as Folk' reunion

Zap2it has confirmed that Harrington, also known for his work on "Dexter," has joined the project as a guest star and will be playing Adam's (Thomas Dekker) father, Ethan Conant. Emily Holmes ("Snakes on a Plane") has also been cast in a guest-starring role: Cassie's (Britt Robertson) deceased mother, Amelia Blake.

"The Secret Circle" follows Cassie as she moves to New Salem and discovers she is part of a secret coven of witches and may also be the key that will unlock a centuries-old battle of good versus evil.  Thomas, Ethan and Amelia were all part of their own coven when they were teenagers and share a complicated history.
