Despite its tantalizing title, Wall Street Cowboy must rank as one of the lesser Roy Rogers films. The story is set in motion by a crooked cartel of stock marketeers who hope to swindle Rogers out of his ranch. It seems that his property is rich with the valuable mineral molybdenum, which the villains want to use for their steel-mining activities. Unable to pay his mortgage thanks to the chicanery of fiancier Niles (Ivan Miller), Roy must rely on the help of an old enemy-turned-friend named Hammond (Pierre Watkin). With a plot that seems more suitable to Charlie Sheen and Michael Douglas than Roy Rogers, Wall Street Cowboy is a major disappointment when compared to the star's promising earlier efforts.
