Production on the fourth season of Big Love is about to get underway.

Before filming can begin, however, producers must first make a couple cast additions. As first reported by Michael Ausiello, the HBO series is seeking actors for two pivotal new roles:

• Christie: Barb's pre-teen niece and Cindy's daughter. A major troublemaker.
• Dale: An empathetic, closeted gay Mormon. A partner in a big-time accounting firm, will become the new Trustee of the Juniper Creek Assets and a love interest for Albie!

Both of this Big Love roles are recurring.
