Lucy Lawless, Stuart Townsend, Joe Doyle and Oliver Bell have joined the cast of WGN America’s hit supernatural thriller “Salem,” which begins production on its second season today in Shreveport, LA.

The new season centers on Salem’s most powerful and ruthless witch Mary Sibley (Janet Montgomery, “Made In Jersey,” “Human Target”) as she faces off against new and old adversaries vying for control of the embattled 17th-century village.

It will return to WGN America in April 2015.

Special recurring guest star, Lawless (“Xena: Warrior Princess,” “Spartacus”), plays “Countess Marburg,” one of the last remaining survivors of the legendary line of ancient German witches.

Townsend (“Betrayal,” “The League of Extraordinary Gentlemen”), in a recurring guest role, portrays English aristocrat “Samuel Wainwright” – a doctor looking to uncover the secrets of “Salem” and keep his own from those who would seek to discover them.

Doyle (“Raw”) joins the cast as a series regular in the role of “Baron Sebastian Marburg,” the charming and cultured son of the Countess.

Also added as a series regular is Bell, who reprises his role as the long-lost son of Mary – long believed to be dead, but who was revealed to have been secretly kept alive by Mary’s witches at the end of season one.

Returning as leading cast members are Janet Montgomery, Shane West (“Nikita,” “ER”) as Captain John Alden, Seth Gabel (“Fringe”) as Cotton Mather, Ashley Madekwe (“Revenge”) as Tituba, Tamzin Merchant (“Jane Eyre”) as Anne Hale, Elise Eberle (“The Astronaut Farmer”) as Mercy Lewis and Iddo Goldberg (“Mob City”) as Isaac Walton.
