The FormulaThis is an excellent movie that for some reason never made it big, likely due to its subject matter. The plot revolves around the idea that Nazi scientists discover a means to develop synthetic fuels and lubricants from coal. This of course becomes an issue of utmost importance to the big oil companies. Realizing that with the mass production of synthetic fuel they would no longer be able to control and maintain their colossal profits they set out to keep this "formula" secret - hidden until the appropiate time. This sets the stage for this movie. The acting is high caliber across the board. I highly recommend this movie - it is closer to the truth than most poeple will want to believe.
