class ReverseCast( Movie ):
    character = Datapoint('character')
    def __repr__(self):
        return (u"<{0.__class__.__name__} '{0.character}' on {1}>"
                .format(self, self._printable_name()).encode('utf-8'))
class ReverseCrew( Movie ):
    department = Datapoint('department')
    job = Datapoint('job')
    def __repr__(self):
        return (u"<{0.__class__.__name__} '{0.job}' for {1}>"
                .format(self, self._printable_name()).encode('utf-8'))
