In one scene at the motel where Georgia asks the clerk to send a letter for her, the clerk drinks ice-coffee with a straw from a glass that is about half full. Despite of this, whenever he takes a sip, the sound heard is a gurgling one, which only occurs when one drinks the last bit from the glass.
Chocolate ice cream spills on Georgia's blue jacket. First near her right side lapel, then on her left. But in a later scene, there is a chocolate stain only on her right side. Yet another scene: no chocolate stains.
The three women who can't speak English sit in the back of the bus, one behind Irv, and the two others in the seat behind her. But in one shot, when Georgia is about to show what the Oracle in Delphi was like etc., the seat where the two women were sitting is empty, later, they are there again.
After the mystical visit to Delphi and the oracle, the evening scene is down at a port with a white Greek church high on the mountain like on the Greek Island of Tinos. There is no way to come down from the ancient ruins of Delphi and sit at the sea port of Tinos.
There are many scenes where you can see clearly they were filmed in Spain, not in Greece. Most noticeable, the hotel they stay at the night before going to the beach is the HOTEL MIRAMAR ("sea view" in Spanish). Also the phone in the room is Spanish, some of the machines used in a close-by job-site belong to a Spanish rental company.
