In the original novel, the protagonist was an American engineer who allowed himself to get dirty and ugly by working with the people of a foreign nation, as opposed to the Americans who become brash and ostentatious upon arriving there. Ironically, the term "ugly American" has become turned around to refer to the latter.
In the film, the protagonist was a diplomat who slowly realizes where the U.S. was going wrong in working with the people of a foreign land.
It was Vivien Leigh, actress in a Streetcar named Desire.

Frank Sinatra did not play Sky Masterson in Guys and Dolls; that role went to Marlon Brando. Sinatra had the role of Nathan Detroit.
