HBO definitely knows how to throw a party, and their annual bash to celebrate the Primetime Emmy Awards was no exception. Held in the courtyard at the Pacific Design Center in West Hollywood, guests partied in a huge tent with a theme meant to celebrate their recent 10-episode WWII epic The Pacific, winner of Outstanding Mini-Series.

The big winner for the pay cable network was Temple Grandin, based on the writings by its title subject, an autistic young woman who became, through mentoring and sheer force of will, one of America’s most remarkable success stories. The film’s star Claire Danes, along with co-stars Julia Ormond and David Strathairn, took home acting awards, while the film itself took home Outstanding TV Movie. Al Pacino also took an acting award home for HBO’s You Don’t Know Jack, about the life of Dr. Jack Kavorkian.

Those celebs showed off their Emmy gold, attending the soiree along with the cast of True Blood (including Anna Paquin, Stephen Moyer, Alexander Skarsgaard, Sam Trammell, Rutina Wesley, Nelsan Ellis, Joe Manganiello, Kristin Bauer, Kevin Alejandro, Lindsay Pulsipher, Lindsey Haun, Todd Lowe, Jim Parrack, Marshall Allman, Mariana Klaveno, Ashley Jones, Anna Camp, Michael McMillian and Michelle Forbes), cast members of The Pacific (Jon Seda, Joseph Mazzello, James Badge Dale and Ashton Holmes) with producer Tom Hanks & his wife Rita Wilson, Big Love co-stars Bill Paxton & Chloe Sevigny.  Continued after the jump:
