Grant Show signs up for 'Big Love' role

Grant Show has signed up for a role in Big Love.

Entertainment Weekly reports that the actor will make his first appearance in the show's upcoming fifth season premiere.

He is expected to play a "spiritual marketing guru" who turns up when Margene (Ginnifer Goodwin) is struggling with her jewellery business.

The show's creator Will Scheffer explained: "That's a major part of [Margene's] story - that whole multilevel marketing that he's involved in becomes part of her story. So we see him big time in the middle and late season."

Co-creator Mark V Olson added: "They've got great chemistry and oddly enough he and Bill have great scenes together when they go toe-to-toe."

Big Love returns for a new season on January 16 on HBO.
