Tornado (1943)

Pete Ramsey (Morris) is a hard-working coal miner who falls in love with and marries scheming showgirl Victory Kane (Kelly). Victory presses Pete to fight for the position of the mine superintendent, which he earns. Unable to bear her poor surroundings and unsatisfied with being a miner's wife, Victory decides to climb the social ladder and have an affair with the wealthy owner of the mine, Gary Linden (Conway), unbeknownst to her faithful husband. Suddenly, a ferocious tornado forms and hits the town and the mine, putting everyone's life in danger. For its time, the film has impressive visual effects for the tornado sequence.
