Vicki Vale was created in 1948, the year before the film. Artist Bob Kane based her on Marilyn Monroe, who he met at a Hollywood party. Vicki was a common character in the Batman comics until 1963, when the editors "cleaned house" on Batman's list of regular costars. She made a print comeback in 1977, and has sporadically waxed and waned in importance in that medium, as well as animated cartoons. Kim Basinger played her in Batman (1989).
If Robert Lowery's Batman costume seems a bit ill-fitting, it's because it was tailored for Kirk Alyn, a bigger man. Alyn starred as Superman in Superman (1948) and Atom Man vs. Superman (1950). Lowery had a terrible time trying to see out of the poorly designed Batman mask.
The titles of each chapter have little or nothing to do with what happens in them. The only possible exception is Chapter 15: Batman Victorious.
An animated picture of Batman as played by Robert Lowery appears in the opening credits of The Pink Panther Strikes Again (1976).
In Chapter 1 police are summoned to a robbery on Ellsworth Ave. This is a nod to Whitney Ellsworth, an editor at DC comics. He was DC's "movie contact" and a consultant on all of its comic book-inspired serials.
