Re: Can you track the comic source?
BATMAN BEGINS also draws pretty heavily from BATMAN #0 after ZERO HOUR in terms of the origin elements. It also kind of adapted sequences from Tom Mankiewicz's old THE BATMAN script, the script that later evolved into Burton's BATMAN.
Writer and Lyricist of GOTHAM'S KNIGHT: THE BATMAN MUSICAL
