Meet The ‘Girls': Allison Williams

HBO’s new series about four twenty-something “Girls” living and loving in the Big Apple debuts this weekend, and we couldn’t be more excited to make the acquaintance of Hannah, Marnie, Jessa and Shoshanna.

In anticipation of the comedy’s debut, we’ve been introducing you to the real girls behind “Girls.” Yesterday you met writer-director-actor Lena Dunham, and today, Allison Williams (who plays straight-laced Marnie) is in the spotlight.

Who she is: Let’s just get this out of the way: Yes, Allison is the daughter of “NBC Nightly News” anchor Brian Williams. But with the debut of “Girls,” the Yale graduate is paving her own path on the small-screen. Allison graduated from the Ivy in 2010, where she flexed her comedy muscles in the improv troupe Just Add Water.

What she’s done: “Girls” is Allison’s biggest project to date, but you might recognize the pretty brunette from her guest spots on “American Dreams” and “The League.” She also polished a posh accent to portray Princess Kate in the Funny or Die web series, “Will & Kate: Before Happily Ever After.” Her pronunciation of Bieber is pretty great.

Marnie according to Allison: “She lives with Lena Dunham’s character Hannah. She likes to think she has it together. She’s poised. She’s focused on her career, but she’s not quite sure what she’s passionate about in life. And she has a boyfriend. It’s kind of the balancing of all of these different life events, coming of age and all of that in New York, trying to figure out who you are, what you want. These are all big questions.”
