Watch: ‘Salem’ Season 2 Trailer Gives First Glimpse of Lucy Lawless, Stuart Townsend

The new “Salem” trailer provides a lullaby for those who wish to never sleep again.

WGN released the spooky new trailer Monday, which gives fans their first look at new cast members Lucy Lawless (“Xena: Warrior Princess”) and Stuart Townsend (“The League of Extraordinary Gentlemen”).

Lawless will play Countess Marburg, a witch descended from a line of ancient German witches, while Townsend will play English doctor Samuel Wainwright.

The new trailer features eerie imagery aplenty; the appearance of the word “War” spelled out in flames forecasts the season’s focus on the so-called Witch War.

Series regulars Janet Montgomery, Shane West, Seth Gabel and more reprise their roles in the historical drama.

Season two of “Salem” bows on WGN America on Sunday, April 5.
