James Marsters has signed up to return to Hawaii Five-0.

The actor appeared in the show's pilot as Victor Hesse, who murdered McGarrett's father.

Hawaii Five-0's executive producer Peter Lenkov has now told TV Guide that Hesse will return in the Christmas episode.

He added that Hesse will have links to the villain Wo Fat, who appeared in the original Hawaii Five-O series.

"There's buzz about Tia Carrere being Wo Fat," Lenkov said. "But we do have a man in mind."

Hawaii Five-0 continues on Mondays at 10/9c on CBS.
