In this episode, it is established that Barbara Gordon is Commissioner Gordon's only child, and she has no children. However, in "The Bat's Kow Tow," Gordon says that he has grandchildren.
It's interesting that Commissioner Gordon, Chief O'Hara, Bruce and Dick are in Barbara's apartment next door to where she is being held. Yet they do not hear the gun shots that the thugs make when demonstrating what will happen to the Commissioner if Barbara does not marry the Penguin!
Bruce Wayne: How does it feel to have a license?
Dick Grayson: Well, it's gonna be a little easier on Batman now that Robin can drive the Batmobile.
Batman: Well, we've managed to clip Catwoman's claws once again. She won't be troubling Gotham City for a long while.
Robin: She sure led us a chase, Batman. If I never hear another one of those meows it will be too soon.
Batman: I'm afraid your eardrums aren't going to get much of a rest, or had you forgotten that Bruce Wayne and Dick Grayson invited Chief O'Hara and Commissioner Gordon to the opera tonight?
Batman: I think you should acquire a taste for opera, Robin, as one does for poetry and olives.
Batgirl: (to Alfred) You tricked me into revealing my secret by posing as a minister!
Alfred: (To Batgirl) Very well, you have my word as a gentlemen's gentlemen, that no one will ever learn your secret from me.
Batman: It's Alfred's emergency belt buckle Batcall signal. He's in trouble.
Bruce: (As Dick prepares to take his first drive after obtaining his license) Remember, this is not the Batmobile.
The "Barbara Gordon" version of Batgirl was specifically created for the series and was later written into the comic books. Several years later, Barbara was shot and left a paraplegic by the Joker in the graphic novel The Killing Joke. Also, Aunt Harriet remained a semi-regular character in the comics until she was phased out in the mid-1970's.
Batgirl (Barbara Gordon) wasn't the first heroine in the Bat-comics. Batwoman (a.k.a. Kathy Kane) made her debut in Detective Comics #233 in July 1956. In April 1961 DC Comics introduced Batwoman's niece Betty Kane (who had a thing for Dick Grayson until 1983) a.k.a. Bat-Girl in Batman #139. Both Batwoman & Bat-Girl were gone in 1964, but were back in 1977 as guest stars in the comic book spin-off Batman Family stariing Robin & Batgirl which debuted in 1975 and ended in 1978. Tragically, Kathy Kane/Batwoman was killed off in Detective Comics #485 ("The Vengeance Vow," August-September 1979) in which she was treacherously slain by The League Of Assassins.
The Batgirlcycle was reconstructed out of a Yamaha YDS-5E. In the presentation reel, Batgirl rode a black, less feminine cycle.
The showcasing of next week's villains at show's end attempted to bridge the gap between the episodes, now that the show was seen once a week.
In this episode, Barbara Gordon has recently returned from four years of college, and Richard Grayson gets his driver's license on his birthday and can now drive The Batmobile!
This season, all of the action word titles which appear during the climactic fight sequences were still inserted in between scenes, with an added twist: they now flash.
Producer Howie Horwitz made a 7 minute film, which was never aired, introducing the Batgirl character, with aide from The Dynamic Duo in confronting the villain, the Killer Moth, in order to convince ABC that the addition of the new character would help the ratings. The network liked it and decided to give the Batman TV series a chance at a third season.
