Patriarch Bill Henrickson (Bill Paxton) struggles to keep his three wives happy in HBO's polygamist family drama "Big Love." So, what's the secret to a successful triple marriage? "I don't think there's much of a secret because I don't think he does it very well," onscreen wife No. 1 Jeanne Tripplehorn joked after Season 2's June 7 premiere at ArcLight's Cinerama Dome in Hollywood. But family ties remained strong down the block at Boulevard3 during a homey afterparty complete with cast family portraits adorning the walls -- because when it comes down to it, Paxton said, "It's all about love."
