Allison Williams cast in NBC's 'Peter Pan,' so dad Brian Williams shows off a family photo on 'Nightly News'

Brian Williams has pretty good comedy chops, as we know from his multiple "30 Rock" cameos, and the NBC anchor showed them off again during an unusual news story on Wednesday's "NBC Nightly News" broadcast. He reported that his daughter, Allison Williams, has been cast as the lead in the network's live musical of "Peter Pan."
