Grace Lamont, Harvey Dent's fiancee, is played by Murphy Cross, who also played a lady friend of Richard Moll's character, Bull Shannon, on the TV series Night Court.
When Two-Face opens his wallet to give Min and Max their cut of the money stolen from the bookies, the number 666 is visible on his credit card in his wallet.
The final shot, in which Two-Face's coin lands good heads, was used in both live-action movies Batman Forever and The Dark Knight, as Two-Face (Tommy Lee Jones and Aaron Eckhart, respectively) fall to their deaths.
The part where Batman throws multiple coins at Two-Face while he is flipping his coin was also later copied in "Batman Forever".
In the previous episode, Two-Face Part I, Two-Face's hair, neckline, and hand are clearly undamaged and unscarred after the accident. However, in this episode his hair is discolored and his neck is scarred and his left hand is also damaged.
When Two-Face looks in his wallet, there is a card registered to Two-Face himself, rather than Harvey Dent.
