With no air date set yet for the fourth season of GirlsHBO began teasing the further single-girl adventures of Lena Dunham’s Hannah Horvath as she retreats to the Iowa Writers’ Workshop, away from her complex b.f. Adam (Adam Driver). But in this teaser, you’ll see the city girl needs some help from her production crew during her romp in the country. Guest stars next season include Natasha Lyonne, Zachary Quinto, Maude Apatow, Jason Ritter and Gillian Jacobs among others.  Dunham’s book of personal essays Not That Kind of Girl: A Young Woman Tells You What She’s “Learned” is due out Sept. 30 from Random House.  As reported by Deadline, the bid for Dunham’s book reached $3.6 million in October 2012.
