All this talk of the battle wagons has me thinking how much I always enjoyed the movie, "Sink the Bismark", and how revolutionary it was when released. Between the actual footage, the optical effects, and the realistic use of miniatures, it set a new standard in special EFX. It was also a classic story that was able to capture the desperation of the RN to sink that monster and the brave sailors on both sides who fought the battles.
A real classic movie about BBs.
