This is a sunny, bouncy early-80s softcore romance flick with a lot of cheesy musical montages, Greek island nude beaches, and mostly-hinted-at threesomes. Watching this film, you will:
In terms of the Greek scenery, and the light tone, this would make a great double feature with 'Mamma Mia' (https://trakt.tv/movies/mamma-mia-20080).
The story here is paper thin but the filming location Santorini, Greece would make any movie enjoyable. Stunning. The only word to describe the location. The fabricated menage a trois between our stars and the endless topless beaches are indeed surpassed by the beauty of the Greek Isles. It made me want to jump on a plane and be there tomorrow. Funny line when Daryl Hannah tells Michael one of her secrets - when she was young she always dreamed of being a mermaid, and this was two years before "Splash".
One of the first films of Daryl Hanna (nice).
