* DirectedByCastMember: Paul Fusco directed six episodes.
* EditedForSyndication:
** Unfortunately, this [[http://en.wikipedia.org/wiki/ALF_(TV_series)#DVD_releases carried over]] to the [=DVD=] releases and Hulu.
** Also, the first version of the theme music was re-recorded in the key of C for some reason (it was originally in the key of D).
* ExecutiveMeddling: In-universe in an episode of the AnimatedAdaptation; Gordon has written a movie script for a drama called ''Yo, Ma'' and it's bought... but the powers that be use it as the basis for the latest ''Gutsquisher'' action extravaganza.
* HeyItsThatGuy:

* MissingEpisode: [[ChristmasEpisode ALF's Special Christmas]] (two episodes) was skipped in Japan for various reasons. However, it did not air until 2009.
* NamesTheSame: The "Tanner" family on this show predated [[Series/FullHouse the other Tanners]] by a year.
* OldShame:
** None of the main human cast members had any major success after ALF. Max Wright continues to act and received a Tony nomination in 1993. The other three regulars have since retired from acting. Wright wanted nothing to do with the show for a long time afterwards, but later changed his mind, acknowledging in interviews how much joy ALF (the show and character) has brought to the world over the years.
** Averted for most people who ''guest starred'' on ALF, such as Jack Riley and Teresa Ganzel, who have all stated that being on the show was a lot of fun for them. Ganzel had heard of the technical nightmares beforehand, but appeared on the show anyway [[AwesomeDearBoy just because she thought it'd be cool.]]
* ScrewedByTheNetwork: [=NBC=] promised that even if they canceled the show, they would make sure there would be an episode to resolve the Season 4 cliffhanger; they went back on that.
* TroubledProduction: It has been described as being what Hell would be like for actors when they die. Due to the constant arduously technical demands of making the ALF puppet come to life, to film a 22 minute episode it took 20-25 full hours. It was incredibly demanding, and reportedly almost everyone on set was miserable.
* WhatCouldHaveBeen:
** The last ALF comics issue ended with a NoFourthWall story where ALF presented snippets of stories that would have been seen in the comic if it hadn't been canceled. Highlights include a ''Film/ThelmaAndLouise'' parody with Kate and Dorothy, a Melmac version of the {{ComicBook/Watchmen}} called "The Washmen" (superheroes who run a laundromat), the revelation that Lynn would move out and get her own apartment, and a story where ALF and Brian go for a ride in ALF's spaceship and end up getting lost in space.
** WordOfGod says that had ALF gone on for a fifth season, the setting would have been changed from the Tanner home to a military base. Somewhat reminiscent of ''Series/ThePhilSilversShow'', new episodes would have focused on the military trying to keep track of mischievous ALF in the same way the Tanners did for the first four seasons. The concept was later reworked into the MadeForTVMovie ''Film/ProjectALF''.
