- Directed by Cast Member:
- Paul Fusco directed six episodes.
- Anne Meara, who played Kate's mother, wrote a single episode.
- Edited for Syndication:
- Unfortunately, this 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).
- Executive Meddling: In-universe in an episode of the Animated Adaptation; 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.
- Missing Episode: ALF's Special Christmas (two episodes) was skipped in Japan for various reasons. However, it did not air until 2009.
- Name's the Same: The "Tanner" family on this show predated the other Tanners by a year.
- Old Shame:
- None of the main human cast members had any major success after ALF. Max Wright continued to act until shortly before his death in 2019, 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 just because she thought it'd be cool.
- Screwed by the Network: 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.
- Troubled Production:
- 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.
- One of the writers, Jerry Stahl, worked on the show while in the midst of a nightmarish heroin addiction, which he detailed in his memoir Permanent Midnight, at one point hallucinating the puppet attacking him while he was high in a bathroom stall.
- What Could Have Been:
- During the show's run, Disney chairman and CEO Michael Eisner actually attempted to purchase the series outright before Alien Productions made a syndication deal with Lorimar-Telepictures. (Ironically, years later Disney acquired the assets of Marvel Comics, publishers of the comic adaptation, while Lorimar had long since been absorbed into Warner Bros., owners of Marvel's perennial rival DC Comics.)
- The last ALF comics issue ended with a No Fourth Wall story where ALF presented snippets of stories that would have been seen in the comic if it hadn't been canceled. Highlights include a Thelma & Louise parody with Kate and Dorothy, a Melmac version of the 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.
- Word of God 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 The Phil Silvers Show, 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 Made-for-TV Movie Project: ALF.
