Arnie did about twenty Japanese commercials in the 80s and 90s, and they're all insane. I'm not sure what product is being advertised here, but I can only presume it's some kind of liquid hallucinogenic.
We only ever see the same handful of video clips from WW2 that I'm always amazed when shots like this pop up from archives. A pre dreadnought of all things firing point blank into a city is insane and someone filmed it. People just gathering to watch is equally crazy.
