Kieran Culkin and Claire Danes worked together on Burr Steers’ 2002 indie “Igby Goes Down,” in which Culkin played the angst-ridden 17-year-old title character to Danes’ slightly older Manhattan socialite Sookie Sapperstein. All these years later, Danes is visibly pregnant, and they chat like old pals about the difficulty of naming her third child with Hugh Dancy. “‘Cyrus,’ we came to pretty readily. ‘Rowan,’ we had to fight harder for. This one is impossible,” she says. “I realized the movie you and I did together is over half of our lives ago,” Culkin says.
