There are favorites and there are favorites. This track from the magnificent composer Eric Sera has to be my favorite soundtrack of all time. The film "The Big Blue" or Le Grand Bleu" that dates back to almost 1980 is not a bit less magnificent. For those reminiscent of Greece and Greek islands or to anyone that has never seen this masterpiece, I highly recommend watching this film. The film is almost entirely filmed on the Greek islands as well as some scenes in the beautiful Taormina (Sicily). The scenes in Greece are mainly from a tiny island called Amorgos with dazzling scenery.
By the way, the American version and the European version differ significantly. To get the full flavor of this masterpiece try to get hold of a copy of the extended version (also called version longue or director's cut).
