After Vicky'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 Vicky's hand.
After Maria Elena moves in, they are having breakfast outdoors. Juan Antonio serves coffee for Cristina and takes the sugar bowl which is in front of Maria Elena in the foreground, and puts it in front of Cristina. The sugar bowl travels back and forth (three times) during the scene.
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.
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.
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.
Cristina gets sick when they are at Oviedo for the week-end. The doctor goes to her hotel room and advises 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.
During the flights in the Piper twin-engine aircraft, the airspeed indicator reads zero and the altitude indicator is flagged, showing that it is unpowered. This would indicate that the aircraft is not running and is sitting on the ground.
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.
The 5-6 time-zone differential between Barcelona and New York, does not relate to the relatively large day/night timezone differentials shown in several scenes in the film. In some instances, the flows of the day, appear reversed from what they they would actually be.
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.
