Of all the actresses on HBO's “Girls” (Sundays at 10:30 p.m. ET) Zosia Mamet is the least like her character. “I don’t watch much television,” Mamet, who plays "Sex and the City"-obsessed Shoshanna, told HuffPost TV. “My old TV agent used to always get mad at me because he’d send me out on auditions and I’d be like, ‘What’s this show?’ and he’d be like, ‘It’s literally the top show on television.’ I wasn’t allowed to watch TV as a kid.” About that childhood: Mamet’s mother is, of course, actress Lindsay Crouse, and her father is writer David Mamet. “I thought about changing my name when I started working,” Mamet said. “But I was like, ‘Fuck that. It’s my name, I don’t want to change it.’” The actress has been working since she was 17, and has appeared on “Parenthood,” “The United States of Tara” and -- most notably -- “Mad Men,” as Peggy’s photographer friend Joyce. On “Girls,” Mamet’s Shoshanna is the youngest of four 20-something women (played by show creator Lena Dunham, Allison Williams and Jemima Kirke) navigating life and love in Manhattan. She spoke to HuffPost TV about landing a job on the series, the danger of being typecast as an actress and what happens when she encounters fans of her father on auditions. How did you get involved in the show? It's actually a little bit of a funny story. I got cast while I was shooting a movie in upstate New York, this small indie film, and we were working really really crazy hours. I was in almost every scene in the movie and I had what I now think was pneumonia. I was deathly ill and I got this audition. Everyone had gone away for the weekend, and I convinced this one PA who was lagging around to not go to church with her family and said, "Make this tape with me." I made it in a room in this abandoned barn -- with terrible, terrible wireless so I almost didn’t get the tape to send -- and sent it off being like, "Well, that'll never happen." And then I got the job. The four of you have great chemistry. Did that take time to develop? We do [have great chemistry]. It kind of happened very organically. Lena is super specific about the people that she casts and she has a clear vision of what she wants. I feel like, thankfully, everybody fit so well into the roles that all of our chemistry magically seemed to work naturally. We shot the pilot in the fall and didn't start shooting the show until the spring so there was a long lag time in between. We all showed up and got to work and immediately became dear, dear friends. Your character really reminds me of Gretchen Wieners (Lacy Chabert) in "Mean Girls." Did you have anyone in mind when you read the script? I really didn't, actually. Shoshanna is like the exact opposite of me as a human. She is nothing like me. I'm a little bit of a weirdo -- I'm kind of a loner, I didn't go to college, I spend a lot of my time reading. I've been working since I was 17, so that's sort of been my life. I was never really exposed to those kind of girls, sorority girls or party girls -- not that she's a party girl. It was a really exciting challenge to play this role because she was so different from me. She's a really foreign creature, and I didn't even really think about, "Oh, can I find a comparison" because Lena's writing and her vision were so clear. She writes so much growth into her characters, just on the page already, so it's very natural for us to be figuring out who they are as the season progresses anyway. It never felt forced.
