Several news agencies had this information up in the past few days:
Finally! Several months after polygamy-themed HBO drama Big Love was renewed for a fourth season, the cabler has announced the premiere date for the fourth season of the series - and it will kick off in January 10.
Big Love, which is currently in production, moves on to its new season finding Bill declaring the formation of his own church (with him as leader of course), Joey suffocating Roman to avenge his wife Kathy's death (Roman's not coming from the dead, the creators confirmed, sadly), Barb being excommunicated from the Mormon Church, and Nicki reuniting with daughter Cara Lynn.
Also, another bit of exciting casting news for Big Love season 4 is Sissy Spacek, who is best known for playing the titular character in 1976's high school horror flick Carrie (huge box office and critical hit). On Big Love, she'll star in a multi-episode arc as a Washington, D.C., lobbyist.
Also, Bella Thorne, who plays the daughter of Christian Slater on My Own Worst Enemy, will take on the role of Bill and Barb's daughter Tancy, which was played by Jolean Wejbe for the first three seasons.
