The name of the department store is Miller Frank a reference to Frank Miller who has written multiple Batman comics including The Dark Knight Returns.
One of three episodes to guest star Mark Hamill.
Fan favorite Kevin Conroy, the long-time voice of Batman since the animated series of the early 1990s, lends his voice again as Batman with Mark Hamil reprising his role of the Joker in that series. The characters, including Alred and the Man-Bat, are drawn very similarly to that series, but the Batmobile and the mansion entrance to the Batcave (Shakespeare bust and sliding bookshelf) are from the 1960s TV series.
Highest rated episode of the series. It should be added that the 2nd highest-rated also stars Mark Hamill.
Las time Mark Hamill voicing The Joker.
