Barbara Stanwyk and Joel McCrea star in director Cecil B. DeMille's explosive western, Union Pacific, about the struggle to build America's first transcontinental railroad. Jeff Butler (McCrea), overseer of the Union Pacific's construction, finds a network of schemers bent on sabotage. Most prominent are gamblers Sid Campeau (Brian Donlevy), Jack Cordray (Anthony Quinn) and Dick Allen (Robert Preston). Dick is a former pal of Jeff's, but their relationship changes as they fight over the railroad and over Mollie Monahan (Stanwyck), the railroad's spirited postmistress. Filled with political intrigue stampeding buffalo, train wrecks and attacking Indians, this action-packed spectacle delivers everything you would expect from a Cecil B. DeMille epic.
