The original 1943 Batman serial was heavily censored in 1960s with a new narrator and several overdubbed or cut lines to remove any anti-Japanese content (it was very much a war propaganda film, so the slurs were heavy). It also caused a lot of the music to be replaced since they didn't have an isolated score. It was released that way to home video in 1989 or 1990. However, the original version was finally released to DVD last year. Ironically, it was Sony who released it, since they now own Columbia who made the movie. I own both versions.
