@tsarstepan,
I recently saw it on DVD. In a movie mazagine she admitted that Cary Grant proposed to her but she turned him down for Carlo Ponti. Cary seemed rather depressed in the movie. There were a few TV stars in the movie. The kid was Peterson in the Donna Reed show and the Italian actor Guardino or something....Sophia was escaping from her high society family and end up being nanny to the divorced Dad or widower.
Also, the sun could evaporate the sea water to get salt as is done in Thailand. A salt factory could be built. The sun rays could be harvested to produce electricity. A harbor and resort and maybe some agriculture from desalted water.
Egypt/Libya would be perfect for the purpose.
