"The shifty eyed Japs". Yeah, wow. Harsh. First time you hear that line from the narrator you think, what did he just say?, lol. I'm glad they had the balls not to censor it. It's historical. It's part of Batman history.
I love the Batman introduction in the 1943 serial (it's not from 1942). It describes Batman as the terror striking creature of the night he was created to be.
High atop one of the hills which ring the teaming metropolis of Gotham City a large house rears it's bulk against the dark sky. Outwardly, there's nothing to distinguish this house from any others. But, deep in the cavernous basement of this house, in a chamber hewn from the living rock of the mountain, is the strange, dimly lighted, mysteriously secret Bat's Cave. hidden headquarters of America's number one crime fighter--Batman. Yes, Batman--clad in the somber costume which has struck terror to the heart of many a swaggering denizen of the underworld. Batman--who even now is pondering a plan of a new assault against the forces of crime. A crushing blow against evil in which he which he will have the valuable aid of his young, two-fisted assistant--Robin, the Boy Wonder.
It's the Batman version of the intro to the 1952 Adventures of Superman TV series.
Faster then a speeding bullet. More powerful than a locomotive. Able to leap tall buildings in a single bound---"Look, up in the sky, It's a bird, It's a plane, It's Superman"--Yes, it's Superman--strange visitor from another planet who came to Earth with powers and abilities far beyond those of mortal men. Superman--who can change the course of mighty rivers, bend steel with his bare hands, and who, disguised as Clark Kent, mild mannered reporter for a great metropolitan newspaper, fights the never ending battle for Truth, Justice and the American Way.
