"Game of Thrones" keeps adding a star to its cast ensemble. Australian actress Essie Davis, who is best known for her role in "The Babadook", has been tapped to play a member of a traveling theater troupe for the upcoming sixth season, according to AceShowbiz.

The group is expected to put on a show called "The Bloody Hand" about what happened at King's Landing over the past years. Richard E. Grant is rumored to be the leader of the troupe. His character "specializes in portraying drunken aristocrats."

Davis reportedly portrays a version of Lena Headey's Cersei Lannister in the play. A sneak peek at Davis' version of Cersei has landed online. Maisie Williams' Arya may join the troupe as she is spotted with Davis in one of the set pictures.

Other new additions to the show include Freddie Stroma who is cast as Samwell Tarly's younger brother Dickon, Pilou Asbaek as Theon's uncle Euron Greyjoy, and Max von Sydow as the Three-Eyed Raven replacing Struan Rodger. Ian McShane also joins the cast.
