Allison Williams is a young actress who's making a name for herself in both cable and broadcast television.
She plays Marnie Michaels on the HBO series "Girls," one of the many supportive friends of aspiring Brooklyn writer Hannah Horvath (played by Lena Dunham). Marnie starts out as an art gallery assistant who pursues her own dream of making it in music.
Allison Williams made it in music on broadcast television when she played the title role in a live production of the musical Peter Pan (with Christopher Walken as Captain Hook) in December 2014, the second of NBC's first-Thursday-in-December live stage shows, which the network hopes will become a holiday tradition.
Fun fact: Allison Williams is the daughter of NBC News anchorman Brian Williams. After seeing her dad as a guest on Jon Stewart's "The Daily Show," I'm willing to bet that she gets her performing smarts from him. :-)
