The Smurfs head to Paris in the sequel to their first feature film, but this isn't your average kids flick. Smurfs 2 has some big lessons and questions for kids and grownups alike, like "What is the definition of family?" "Today, more than ever families are designed and defined in totally different ways," says Neil Patrick Harris. "It's not just mom & kids. There's two dads. Single mom. There's mom & dad but they are over here." Movies with Milan catches up with the cast, Smurfs included.
