Audiences checking out off-Broadway's interactive theatrical experience Sleep No More over Thanksgiving weekend may have recognized a famous face roaming around the McKittrick Hotel. Broadway veteran and Tony host Neil Patrick Harris, a self-proclaimed fan of the Macbeth-inspired production, befriended the show's producers and convinced them to let him join the Sleep No More cast for an evening. Harris hopped into a porter uniform to interact with the masked crowds exploring the five-story theater space. The actor, who's serving as co-host on Live with Kelly for the week, gushed about the experience with Kelly Ripa, who was in attendance during his performance. Skip ahead to the 7:45 mark to watch Ripa don one of Sleep No More's signature Venetian masks as Harris dishes about his night in the show.
