In Jazz animated word press website, the quotes of composer Harvey Cohen were published about how he composed the episode "A Bullet for Bullock." Here is the quote. Harvey Cohen - "Shirley Walker, as you know, was the music supervisor/primary composer for 'B:TAS' and kind of set the musical tone for the show: lush, dark, similar to the Elfman scores for the first two films ('89 & '92). With the 'Bullet' score, I was told to write a jazz score but not specifically of any time period. The hard-boiled detective 'film-noir' style felt right. Also, as luck would have it, I got the assignment 2-3 days after Henry Mancini's death in July '94. He and his music were big influences on me, and the score is kind of a tribute to him."
The episode won an Emmy Award for Outstanding Music Direction and Composition.
The episode is based on the October 1992 comics story of the same name from "Detective Comics" (Vol. 1) #651 by Chuck Dixon and Graham Nolan.
