"Now, I'm in the madness," said Alexander Skarsgard as he kicked off his day of press, premieres, and parties at the Sundance Film Festival by taking a moment to chat with and pose for InStyle's pop-up portrait studio (check out the photos in the April issue!) with his co-star from The East, Brit Marling. The madness continued with visits from Felicity Jones of Breathe In, Kristen Bell of The Lifeguard, Lake Bell of In a World, and more.
