Allison Dubois is about to get some company. According to The Hollywood Reporter, Anjelica Huston is going to appear on a six episode arc of the ghost-themed CBS series Medium.

Huston will be playing an investigator for the national firm Ameritips. Her character, Cynthia Keener, will strike a very unusual bargain with Patricia Arquette's character.

Creator/executive producer Glenn Gordon Caron stated, "When we decided to embark on a six-episode arc involving a formidable female character, the challenge was to find an actress who could hold the screen with Patricia while creating sparks of her own. I couldn't be more excited or more inspired (to have Anjelica Huston in the role). The idea of writing for two such extraordinary actresses as we enter our fourth season is exactly the kind of creative kick in the ass we relish on Medium.

The series will return for its forth season in January of 2008.
