TORCHWOOD continues to add to its cast for the upcoming fourth season. Michael Ausiello’s TVLine reports that Alexa Havins has signed on as a series regular. She will play a CIA analyst named Esther Katusi who is saddled with a tremendous amount of faith in human nature and a crush on CIA agent Rex Matheson (the already announced Mekhi Phifer).
Havins is best known for her role as Babe Chandler on All My Children and she will be guest starring in the February 10 episode of Grey’s Anatomy as Thatcher Grey’s noticeably younger girlfriend.
Meanwhile, TV Line also says that Dichen Lachman will guest star in the Torchwood: The New World premiere as a CIA agent. Lachman starred in Dollhouse and recently made an appearance on Hawaii Five-0.
John Barrowman and Eve Myles are reprising their roles as Captain Jack Harkness and Gwen Cooper while the previously announced Bill Pullman will play convicted killer Oswald Jones and Arlene Tur is set to recur as surgeon Vera Juarez.
Torchwood: The New World will air on Starz in the US and BBC One in the UK in summer 2011.
