Where to begin? Perhaps by simply stating "this is a fine film." The black and white photography invites the viewer into an odd story of family intrigue capped by entertaining singing and song. I guess Ansiedad could be classified as a musical, but since all musical numbers are not stylized into the story (all music is on stage within the film reality - the characters are singers by trade) Ansiedad could be classified simply as drama. Hidden within this film is commentary on class structure, pursuing what one loves, and personal redemption. Pedro Infante turns in three fine performances. First as concerned father and husband of Libertad Lamarque, then as grownup twin sons. Apt camera angles and editing combines his twin roles simultaneously into several scenes. Not that I'm an expert, but this film stands as a fine example of the golden age of Mexican cinema.
