who ever thought of 'married heroine'. The theme of most romantic movies centred around single hero and single heroine who would ultimately be married to each other. But what if both are married at the very beginning. This means new themes. May be of family break up and divorce. Marriage of divorced hero and divorced wife. There was one movie 'kabhi kabhi' differeing from usual theme.
