    last_name = fields.String()


class Movie(Schema):

    title = fields.String()
    released = fields.Date()
    cast = fields.List(Actor())


movie = Movie()
output = movie.serialize({'title': 'Good Will Hunting',
                           'released': datetime.date(1998, 1, 9),
                           'cast': [
                               {'first_name': 'Matt', 'last_name': 'Damon'},
                               {'first_name': 'Ben', 'last_name': 'Affleck'},
