Romance films involve romantic love stories recorded in visual media for broadcast in theatres or on television that focus on passion, emotion, and the affectionate romantic involvement of the main characters. Typically their journey through dating, courtship or marriage is featured. These films make the search for romantic love the main plot focus. Occasionally, romance lovers face obstacles such as finances, physical illness, various forms of discrimination, psychological restraints or family resistance. As in all quite strong, deep and close romantic relationships, the tensions of day-to-day life, temptations, and differences in compatibility enter into the plots of romantic films.
