Are you ready to go Camping? Girls' Lena Dunham and Jenni Konner have teamed up once again for the new HBO series, which stars Jennifer Garner [1] as Kathryn, an uptight wife who meticulously plans an outdoor getaway for her husband Walt's (David Tennant) 45th birthday. Unfortunately their already-unhappy marriage gets put to the test when unwanted guests show up and nature throws them a few curveballs. ("It may not be fun. In fact, it may not be fun at all," Kathryn warns.) The comedy also stars Brett Gelman, Arturo del Puerto, Juliette Lewis, Ioni Skye, and Bridget Everett, and arrives on HBO on Oct. 14.
