Diablo Cody's upcoming Showtime comedy pilot The United States of Tara is moving closer to production with the hiring of writer-producer Alexa Junge. According to The Hollywood Reporter, Portia Doubleday and Keir Gilchrist have joined the cast of this proposed sitcom.

In the show, Toni Collette stars as Tara, a wife and mother with multiple-personality syndrome. Junge will be the executive producer should the single-camera series get picked up for additional episodes.

Shooting on the pilot will begin this April in Los Angeles.
