Consider this the Needcoffee version of an Elseworlds story.
After the monster success (pardon the pun) of Jaws, Steven Spielberg had his pick of projects. He passed on Jaws 2, Superman, and Close Encounters of the Third Kind. Spielberg’s love of the pulp/WWII era led him to start preproduction on a promising script from Robert Zemeckis and Bob Gale titled 1941. However, it became clear that this movie was quickly turning into a expensive career-ending disaster. Does Spielberg admit defeat? No, he gives a friend a call.
George Lucas was in pre-production hell. Trying to develop his “Adventures of Luke Starkiller, as taken from the Journal of the Whills, Saga I: The Star Wars” script to screen is proving to be a Herculean effort. Trying to explain to studio executives about Jedi Knights was taking most of his energy. One day, his friend Steven Spielberg gives him a call. During their conversation, Spielberg brought up how they always wanted to work on a project together. He suggests combining the WWII material he has with Lucas’ script and making something unique. A WWII science fantasy.
And in this Elseworlds tale, at least the Japanese accents of the Trade Federation would make sense.
