Continuity: As Cristina walks into Juan Antonio's house for the first time, she is wearing a white blouse with long sleeves. As we first see her, one sleeve (the viewer's left) is three-quarters length and the other is rolled up at the elbow. After a very slight scene shift, but with no time passing, we see Cristina with both sleeves rolled up.
Revealing mistakes: When Juan Antonio receives a phone call in the middle of the night, he reaches over and turns on a lamp. The lamp turns on, then the wall lights up a split second later, revealing the wall's glow to be coming from another light source.
Incorrectly regarded as goofs: Christina gets sick when they are at Oviedo for the week-end. The doctor goes to her hotel room and advices her to rest and tells that she became sick because of her ulcer. In another scene, someone asks for a painkiller and she takes aspirin from her purse, despite the fact that aspirin worsens ulcers. However, she could merely carry aspirin in the event family/friends need it, which is what happens during the movie.
Continuity: After Vicki's hand is shot, the three of them agitated about the situation. During this discussion, no visible signs of the wound can be seen on Vicki's hand.
Continuity: When Vicky and Juan Antonio have dinner the behind shots and face shots of Juan Antonio do not match. In face shots he is leaning forward and his head to the side. On behind shots he sits straight upright.
Incorrectly regarded as goofs: The people in this movie (including the leading man) speak Spanish instead of Catalan. In Barcelona both Spanish and Catalan are spoken. In Oviedo, only Spanish is spoken.
Errors made by characters (possibly deliberate errors by the filmmakers): Oviedo is referred to as part of Catalonia with Vicky continuing her research on "Catalan culture" while she is there. In fact, Oviedo is in Asturias, not Catalonia.
Revealing mistakes: When Cristina wakes up in the middle of the night, she makes herself some coffee. The coffee maker she's seen using is a very large Bialetti Moka Express, or a copy thereof. These seldom operate correctly for less than the maximum amount of coffee, which in this particular instance would be about thirty double espressos. It goes without saying that this is a truly insane amount of coffee for any one person.
Continuity: (At 56:00) After Maria Elena moves in, they are having breakfast outdoors. Juan Antonio serves coffee for Christina and takes the sugar bowl which is in front of Maria Elena in the foreground, and puts it in front of Christina. The sugar bowl travels back and forth (three times) during the scene.
