I know you are probably joking with this post, but some people might actually be unaware of the two made for televison movies released in the mid 1980s featuring the Ewoks:
Joshua Logan was certainly no slouch. Apparently the first one was partially directed by him uncredited because of all the problems they had with John Ford.
I meant the Mr Roberts TV show. It doesn’t really fit in this thread because it can’t be considered a sequel. I suppose they ignored the last 1/3 of the movie and went from there.
The Hidden, a great and mostly overlooked SF film* (that feels like it’s a darker version of Hal Clement’s Needle) spawned a couple of made-for-the-SciFi-channel sequels that were abysmal.
I’m sure the awful sequels to Psycho are pretty well-known, but there was another not in the series – Bates Motel - a made-for-TV “comedy drama” ( Bates Motel (film) - Wikipedia ). There was also another unrelated spinoff that almost got made, but lawyers blocked it. And, just for kicks, Robert Bloch, who wrote the original novel, wrote two sequel novels Psycho II and Psycho House, that were unrelated to any of the films. ( Psycho House - Wikipedia ) You can take your pick of possible Norman Bates stories, kinda like a Follow-Your-Own-Adventure book.
*It also stars Kyle MacLachlan as a weird FBI agent from the Pacific Northwest, just like on Twin Peaks. You could look at it as something that explains how he got that way.
I remember watching the TV series. Was it called Highlander: The Raven? That might be a good thread, TV series based on movies. The Net. Ferris Bueller. The animated series of Bill & Ted, Back to the Future, Attack of the Killer Tomatoes…
Actually, The Net also had a horribly obscure sequel, The Net 2.0. The TV series was a standard episodic 90s conspiracy series, just without aliens (aliens were big in the 90s). The sequel is just the same basic plot but ten years later and without Sandra Bullock or any of the other things that made the original a success.
Oh yes, there is also an excellent sci-fi movie called “The Man From Earth”, about a man who claims to have lived since the stone age. Came out in about 2007, it’s on IMDB’s list of the top 250 sci-fi movies of all time, it’s little known but very well thought of. Even less well known is The Man From Earth: Holocene, which came out straight to the internet earlier this year. They are also planning another sequel or possibly a TV series. The original was excellent, and had a lot of pedigree, the writer being the writer of various Star Trek TOS episodes and suchlike, but the sequel has none of the charm of the original.
Jerome Bixby’s credits go far beyond that. He wrote the excellent 1950s flick It! The Terror from Beyond Space that Dan O’Bannon, Ridley Scott, and company clumsily strip-mined to make the original Alien. Bixby’s script is better. He also wrote the original story it’s a GOOD Life that became on of the creepiest and best-remember Twilight Zone episodes, and he rewrote the script for Fantastic Voyage. Then he went and wrote some Star Trek scripts and The Man from Earth*
I didn’t know about the Man from Earth sequel. Thanks.
*He also wrote a couple of other 1950s SF movies – the unjustly forgotten The Lost Missile and the laughable Mummy-from-Pompeii movie Curse of the Faceless Man.
The TV series (which was actually fairly good, as those things go), was just called Highlander (sometimes given as Highlander: The Series). It starred Adrian Paul as Duncan MacLeod, clansman of the movie’s hero Connor MacLeod. They even talked Christopher Lambert into appearing as Connor in the pilot.
Highlander: The Raven was a spin-off of that, focusing on a female immortal, Amanda, who had appeared several times in Highlander: The Series.
Highlander: The Raven lasted only one season and was god-awful.
The Gods Must Be Crazy was a quirky and amusing low budget indie movie from the 80s.
I originally was going to mention the probably not too obscure The Gods Must Be Crazy II, but when I went to get a link I learned that 3(!) more sequels and a few more unofficial name hanger-ons exist
Paul Gallico wrote a sequel to, “The Poseidon Adventure,” called (natch), “Beyond the Poseidon Adventure.” “TPA (book),” is almost nothing like the movie and, “BTPA (book),” is totally unlike the movie, which starred Michael Caine, that gruff old sea captain Karl Malden and first mate Sally Field. Run, don’t walk from this movie (and book). Rock bottom is too kind a description.
I’ve always thought of John Ford as a vastly overrated director. When he said “I’d rather have a hundred bars of good music than one line of bad dialogue,” he wasn’t kidding!
During the filming, it veered away from being a direct sequel, but *Nosferatu in Venice *was a rather obscure “sequel” to Werner Herzog’s Nosferatu the Vampyre. It returned star Klaus Kinski although he refused to shave his head and don the makeup from the previous film.
