Allison Williams: Marnie Michaels

Allison Williams was cast as Hannah’s tightly wound, deeply insecure, and meticulously structured best friend, Marnie Michaels. After Girls wrapped, Williams pulled off one of the most brilliant genre pivots in recent Hollywood history. She immediately shed her clean-cut millennial image by starring in Jordan Peele’s Oscar-winning horror sensation Get Out. She doubled down on her scream queen credentials by starring in and executive producing the viral sci-fi thriller hit M3GAN, alongside appearing in Showtime's critically acclaimed miniseries Fellow Travelers.
