At one point in the film, Carla (Penelope Cruz) the mistress of Guido Contini (Daniel Day Lewis), is in her small hotel room in Venice seeing Guido leave her to attend to his business as a director. She is disappointed since he did not make love to her. She says that she will be waiting for him to return with her legs open and sits in a very inviting pose on the bed. The reason I am talking about this is because that is a line only Penelope can deliver with so much class. If you wish to see Penelope at her best, then make sure that you watch some of her movies in Spanish directed by Pedro Almodovar.
Nine does have an impressive cast but if you have enjoyed awesome musicals like Chicago or Hairspray or Dreamgirls in recent years, then this might disappoint you. The plot is rather convoluted and lacks coherence (an Italian movie director undergoing a midlife crisis can save neither his career nor his marriage). The movie is good for individual performances by Penelope Cruz, Nicole Kidman, and Marion Cotillard, and I also enjoyed the soundtrack (I had heard Kidman in Moulin Rouge and she was awesome at “Unusual Way” but Marion was a pleasant surprise at “My Husband Makes Movies” and I was not sure if Penelope could sing because the song Volver was not sung by her).
