Watch FMovies. Magician-turned-actor John Calvert, previously the suave leading man of Film Classics' "Falcon" series, is a curious choice to star in the rough-and-tumble western Gold Fever. John Bonar (Calvert) and grizzled old prospector Nugget Jack (Ralph Morgan) strike it rich, whereupon they are besieged by Bill Johnson's (Gene Roth) outlaw gang. Heavily outnumbered, our heroes are forced to rely on brain rather than brawn.
