Question: Did the pair of Levi's used in the movie actually fit all of the actresses, or did they all have their own pair? If it fit them all, did they have multiple pairs?
Question: What island did they film the scenes in Greece?
Answer: According to the IMDb, filming occured on Santorini (also known as Thera or Thira), part of the Cyclades island group.
Answer: It seems nearly impossible that one pair of pants would actually fit four actresses of such different heights and weights. One of the "magic" properites of the pants was that they did manage to fit all the girls in the story, so it's probably safe to assume that different pairs were actually used for filming.
