 of the tornado in the Wizard of Oz, the way it sweeps the horizon back and forth and even today with our eyes, movies like Twister and CGI and the way that you can depict storms realistically, that scene is still frightening in 1939 from the Wizard of Oz where you see that coming tornado, you see that twister churning up the plains, churning up that farmland with its dirt coming closer to Dorothy.
