Big Love has to hurry up and set a premiere date for its fourth season. We need to know how many days to cross off our calendar!

The latest exciting news surrounding this HBO hit is that Sissy Spacek will play a "powerful Washington D.C. lobbyist" for multiple episodes, according to the Los Anegles Times.

The Oscar winner, who has starred in too many hit films to list, is the latest addition to the show. Other actors cast for season four include:

• Bella Thorne, who will replace Jolean Wejbe as Barb and Bill's youngest daughter;
• Ben Koldyke as Dale, a state-appointed trustee and love interest for Alby.
