Italian Region Free import has the original English audio (and optional Italian audio and subtitles). An alien, who adopts the name Thomas Jerome Newton, arrives on Earth and quickly sets about creating enough wealth to allow him to return to his own world. His home world is portrayed as a vast arid land where water is at a premium. With the help of patent lawyer Oliver Farnsworth - who later becomes the CEO of Newton's holding company, World Enterprises - he has a number of original patents that make him very rich. Along the way he meets a number of interesting characters, including Mary-Lou, who falls in love with him and Nathan Brice who works for him. The question of course is whether Newton will ever get to return home.
