"The Olympia shipwreck can be seen in the 1988 Luc Besson movie The Big Blue. It ran aground near shore on Amorgos Island in Greece. The secret of this image lies in the synchronization. To succeed, it took a ray of sunlight to illuminate the underwater landscape, then a wave arrived with the right angle on the dome to have a good view above and below, and finally, the freediver had to hold position facing the wreck. It took a lot of rehearsal."
