Shoshanna Shapiro

Shoshanna is Jessa's younger, bubblier cousin and a surprising source of wisdom -- though lately, she could stand to listen to her own, oft-given advice. After a year of sexual escapades and slacking, she’s graduated late from NYU and is struggling to land a job, throwing a major kink into her 15-year-plan. To make matters worse, she’s failed to win back Ray, who’s been hooking up with Marnie on the sly.

Zosia Mamet

In February 2013, Mamet made her stage debut, playing opposite Matt Lauria in Paul Downs Colaizzo’s critically acclaimed Off-Broadway play ‘Really Really.’ Directed by David Cromer, Mamet plays Leigh, an untrustworthy and manipulative college student. In the aftermath of a wild night of partying, the bonds of friendship are tested and politics come into play. The play continued its run until March 30, 2013.

Mamet starred in the dark comedy ‘Cooler,’ along with Jim Parsons, Sung Kang and Harold Perrineau that screened at the 2012 South by Southwest Festival. The story centers on a high-strung and overly meticulous nurse who must return to Los Angeles to retrieve bone marrow for a transplant.

In 2012, Mamet starred in ‘Rhymes with Banana’ directed by Joseph Muszynski and Peter Hutchings. The independent film is a satirical comedy about two struggling young actresses [Mamet and Jee Young Han] with big dreams, who are coping with rejection and mediocre prospects.

In 2010, Mamet portrayed Sasha in the Academy Award nominated film, ‘The Kids Are All Right’ opposite Mia Wasikowska, Annette Bening, Julianne Moore and Mark Ruffalo. The Lisa Cholodenko film was also recognized with an Independent Spirit Award and Golden Globe Award for Best Film.

Mamet’s other film credits include ‘Spartan’ which was written and directed by David Mamet, and stars Val Kilmer, Derek Luke and William H. Macy; she appeared in the Focus Features relationship dramedy, ‘Greenberg,’ directed by Noah Baumbach and starring Ben Stiller; and in ‘The Last Keepers’ with Aidan Quinn and Virginia Madsen.

Mamet’s television credits include high-profile supporting roles, most notably as a lesbian secretary [Joyce Ramsay] in Season 4 of ‘Mad Men;’ as Courtney in Showtime’s hit series ‘United States of Tara’ written by Academy Award winner Diablo Cody; as Kelsey on NBC’s hit show ‘Parenthood,’ which is based on the 1989 film of the same title; and ‘The Unit’ from director David Mamet. Mamet also lends her voice to the Fox animated series ‘High School USA!’ Written and created by Dino Stamatopoulos, the animated series is a parody of Archie Comics. Mamet voices the ditzy blonde high school student Amber Lamber.

Mamet will next star in ‘Shiva & May’ alongside Jessica Biel. Biel and Mamet play long-lost sisters in the indie thriller from writer and director Diane Bell. Mamet will also appear in Eric Weber’s ‘Outliving Emily’ with Thomas Mann and Olympia Dukakis. The indie film is based on Weber’s short story about the tumultuous marriage of a couple, Tim and Emily Hanratty, over half a century. The film, comprised of six vignettes, is portrayed by twelve different actors and also stars Alexis Bledel and Phylicia Rashad. Mamet completed production on Steven Bernstein’s ‘Dominion.’ Set in the 1950s, the film centers on the final days of Welsh poet Dylan Thomas. The indie drama stars John Malkovich, Rhys Ifans and Rodrigo Santoro. Mamet recently wrapped indie film ‘Goldbricks in Bloom’ by writer and director Danny Sangra. The film follows a young group of creatives in New York that question the value of their work and lives.

Originally from Randolph, Vermont, Mamet is the daughter of David Mamet and Lindsay Crouse. Mamet's maternal grandfather was Russel Crouse, who co-wrote such classic American musicals as "Anything Goes" and "The Sound of Music." She currently resides in New York City.
