It's a great film, traditional romance, only the girls go on vacation in different countries, finding love there in the most unlikely places.
I've seen it a few times, it never really gets old. I like Kat Winslet's character better than Diaz's, as she's more beleviable and loveable.
Parts of this movie were filmed in the area that I live (the snowy field outside of Iris' cottage) I never actually saw any of the actors while they were filming, but they blocked off the whole church yard and park, that I usually walked through on my way home from work, so I had to go the really long way round, taking me an hour out of my way. :D
