Actor Allusion: Art Carney's excessive noodling with a device in exactly the same way Ed Norton did in The Honeymooners, complete with an Imperial Guard yelling "Will you just get on with it?!" in the same way as Ralph Kramden.
Kevin: It's just not the same without a fat man threatening violence.
Carrie Fisher once asked for and received a copy of this special from Lucas sometime down the line as payment for a DVD commentary — she says she uses it to drive out guests at her parties who overstay their welcome.
Executive Meddling: Originally, George Lucas was to be much more involved in the project — he helped to write the first draft of the script (a standard-issue Star Wars adventure revolving around Life Day) and contributed to the animated Boba Fett segment. Sounds great so far, but then the CBS execs decided it had to be a variety show spectacular of the type that was relentlessly inflicted on unsuspecting audiences of the 1970s. Lucas, by this time, had gone off to concentrate on The Empire Strikes Back, and other hands — namely Pat Proft and Bruce freaking Vilanch — rewrote the script to fit the network's wishes.
A more beneficial example happened (although it's not completely beneficial so much as lesser of two evils): The entire Mind Evaporator sequence was originally intended to be quite explicitly a porn tape. However, it was toned down in order to meet CBS's censorship standards, although the implications of what the Mind Evaporator actually was are still present.
Franchise Killer: Averted... which is kind of amazing considering the result. Let's just say it's a good thing that Lucas was already making Empire when this came out; otherwise it might have been the end of Star Wars entirely.
Inverted in the case of Lev Mailer, the guy who played the Jerkass officer bullying the store owner in the special: He was one of the few people involved in its production who actually enjoyed the experience.
Harrison "Stone-Face" Ford: So embarrassed, he could barely keep from fleeing the room when Conan O'Brien surprised him with a clip.
"It was a wonderful time, but I had no idea it was even a part of the whole Star Wars thing... It's odd. I've gotten so many letters and requests for autographed photos from that thing. I just remember singing to a bunch of people with funny heads."
She didn't know it was a Star Wars production?! That can only mean the production team were probably too embarrassed to acknowledge this special as Star Wars-related. Ouch.
Anthony Daniels (C-3PO) claimed in an interview that he still has his copy of the script, but is too embarrassed to even look at it.
Throw It In: Lev Mailer and Art Carney ad-libbed the scene where his character and Saun Dann were interacting in the trading area. More specifically, they chose to do the scene in a manner similar to the "Bully and Idiot" comedy routine.
What Could Have Been: The special was supposed to segue into The Empire Strikes Back, but unfortunately the only part of the special that got it right was the animated segment.
