El insaciable

Apparently a brief exchange between the adolescent boy (Bobby Anderson) and his father (Raymond Burr) in which the father tells him that opportunity only comes around once, is the reason why Anderson morphs into the social climbing and ruthless business tycoon played by Zachary Scott. It hardly seems like enough of an influence to change a nice kid into a prototypical (and stereotypical) greedy capitalist millionaire. Though it's difficult to establish a connection between the two, Scott makes a believable social climber, and the story has a pretty good trajectory from his adolescence through dark mansions and well furnished offices with New York skyline views, to a finale gala event where Scott is organizing a philanthropy to unload some of his millions and ease his conscience. Ulmer doles out the action in bits and pieces, but delivers a pretty memorable ending.
