Before watching the movie:
This is one of those movies that seem to boil down to a log line and nothing more enters the general consciousness. This is three romances centered wishes at Trevi Fountain. I know nothing more than this. It was shot on location because all the big Hollywood pictures were shot in Italy in those days. It seems to be a particularly fondly remembered example, but nobody seems to talk about much other than “shot on location” and “three American women in Rome wish for love”.
It’s in color and CinemaScope, so the Italian views won’t be squandered. In fact, I get the impression they’re the best part of the movie for a lot of people.
