...Oh, and if you want to see WWII-era Americans fighting Godzilla (of a sort), the Heisei-era Godzilla vs. King Ghidorah actually goes into that. It's got a bonkers time-travel plot about people from the future plotting to meddle with Japan's history, and in the process, the action moves to Americans fighting the pre-mutation Godzillasaur in the 1940s. Includes the most pathetic battle-cry ever written: "Take that, you dinosaur!"
