Bruce Timm said of this episode, "This is such an adult show that I bet kids don't like it. There's not a whole lot of action and Batman's hardly in it. It's a lot of talking heads. But it works on such a powerful emotional level that I'm sure that anyone over the age of six is going to get sucked right into it. It's absolutely compelling. They always talk about the BATMAN films as being oh, so psychological. Bull. This episode is a compelling psychological drama."
Grace Lamont made no further appearances in the television shows, but did appear in the comics. In Batman & Robin Adventures #1 and Batman & Robin Adventures Vol #2, she falls victim to a nefarious plot by the Joker: he enrages Two-Face by suggesting that Grace and Bruce Wayne are a couple. Two-Face kidnaps Dick and threatens to kill him, but in the end Grace stabs Two-Face's disfigured face with his damaged coin. The story ends with the implication that their relationship is over. In Batman & Robin Adventures #22, however, Two-Face calls Grace via payphone and warns her to get out of her apartment before Little Jonni Infantino, who threatens to harm Grace when Two-Face refuses to give information on one of Harvey Dent's last cases, can send his men after her. She is later seen crying while telling Bruce Wayne that Harvey just saved her life. This comic may indicate that Grace still loves Harvey and that there is still hope for him.
During the beginning of the robbery Two-Face tells everyone "For the next five minutes I'm in control!" which was spoken by Al Pacino in Dog Day Afternoon (1975). Coincidentally, Pacino was offered the role of Two-Face.
Pause at the right time and you'll see that Harvey has since actually gotten an ATM card in the name of his alias.
Alfred asks Batman if they should warn the second bank of Gotham when looking at the list of places Two Face has been. The second bank of Gotham is Two Face's target in the opening of Batman Forever (1995).
