Ireland will play Logan, a classmate of Hannah's (creator and star Lena Dunham) who is rich and beautiful but also cold.
Hannah and Logan's classmates at the Iowa Writer’s Workshop will be played by Desiree Akhavan ("Nose Job," "The Slope") and Peter Mark Kendall ("Public Morals," "The Leftovers").
Ireland's work on Broadway includes The Big Knife, After Miss Julie and reasons to be pretty. Her screen credits include "Homeland" and "Mildred Pierce." She will star as Christina Rosa in "The Divide," which premieres in July.
