Allison Williams

Who she is on the show: Marnie Michaels
Hannah Horvath’s professional and personal shortcomings could not be more apparent than when she stands beside her mature and responsible roommate, Marnie Michaels. Already dubbed as the “Charlotte York” (Sex and the City) of Girls, Michaels is the “adult” of their apartment, i.e. the one with the stable job at an art gallery and a longtime boyfriend. However, the precedence she puts on the idea of her security keeps her from actually admitting she might be miserable in both of her commitments.
