Wouldn’t be the same without Rickman.
We have a Cumberbatch.
A pre-teen girl finds the Zoltar, wakes up as a 30 year old, and has an affair with the now adult Josh…ugh, never mind.
Not really a ‘sequel’ in any sense, but the film adaptation of L.A. Confidential had a very similar plot of Who Framed Roger Rabbit, and I’d love to see a film adaptation of White Jazz as a direct sequel (although you’d obviously have to make some adjustments given the different outcomes of characters from the novel and film versions of L.A. Confidential, and Ellroy will likely never allow someone to make another film adaptation of his novels while he is alive.

There was going to be a prequel for that but work on it started the year after Schindler’s List and Spielberg decided he had enough of Nazis.
You see, part of the plot had Roger in Europe for WWII.
??? True Grit is a remake of…True Grit. They did a really good job at remaking it, and I would love to see a remake of Unforgiven, as well. I’m not sure I understand your response.
Angela Jones’s character Esmerelda Villalobos (the cab driver) got a sort-of spinoff in Curdled. Her character’s name is different, but she’s still intrigued by the criminal life and working cleaning up crime scenes. Tarantino’s company A Band Apart produced it, and other characters from the Tarantinoverse pop up, implying it’s set within the same continuity as his other films.
See, that’s the beauty of it… the trailer will tease that. We’ll see a girl walk into their classroom from behind. Her arrival is a big part of the film, with lines like “A new girl?” “Hope she’s hot.” “If she is, she’s gonna be stuck up.” “Heard she’s from New York City, so yeah…”
It’s one of the many conversations between the boys throughout the movie… all 3 hours, but it’ll be worth it. Along with an answer to “If Mickey’s a mouse, and Pluto’s a dog, then what’s Goofy?” There’s a good hour of the boys walking along a golf cart path and discussing mysteries like these.
The last scene of the movie is the “showing the new girl into class” scene. Camera dollies around her to focus on her huge glasses, messy black hair and retainer. The boys give each other a “told you so” look, and the audience thinks “What a clever film, to upend the cultural zeitgeist like this. A movie with absolutely nothing going for it… we should see this again!”
The Coen Brothers version of True Grit was a direct adaptation of Portis’ novel (not a remake of the 1969 film, which deviated significantly on several points), and is the closest thing you’ll see to their vision of Unforgiven as they aren’t particularly interested in the Western as a genre. Even aside from the metatext of Eastwood undermining his own signature “Man With No Name” character, I can’t see anything that a remake would bring to the story which would make it necessary or an improvement on the original.

Something good could be done. But we know it won’t. It has to look like a good movie to get the original cast to participate, except they’re even older now so they need to change things up a lot. I think they just need a few members of the original cast, maybe just briefly, and a new cast based on the reboot of the ‘Galax Quest’ TV show. Maybe the new commander of the NSEA Protector is some bald guy, and his second in command is one of those whatever Sarris was aliens. They could do a tribute to Alexander Dane or just have him refuse to participate in any more Galaxy Quest business. I wish something would get done, but I’m afraid we’d just see a simple variation of their last adventure lacking the spirit of the genre that made the original so special.
Thank you for the further context on your response.
It had comic books, a tv series and several tv movies.
The Breakfast Club. Either a sequel revisiting those characters years later (at a high school reunion?), or a remake with some of today’s teenagers.
The story of prostitutes putting up a bounty to kill some cowboys was just a pretext to make a Clint Eastwood western. Remove the Eastwood memes and you could have a better movie.
A few I can think of, more for remakes specifically mentioned in the OP, rather than sequels. Although considering who owns the rights, it would never happen IMHO.
The Black Hole (1979) - gothic horror movie in space? A mad man who refuses to stop his obsessions and continues by killing and repurposing those whom he was entrusted with? A conflicted crew that reacts in very human ways leading to bad consequences from all? Update the androids and modify the smarmy “heroic” robots and update the graphics while (ideally) keeping the model work for the ships (yes, I know, never happen) and I’d be throwing my money at it!
Similarly:
The Black Cauldron (1985) - much of the above, treat the source a bit more seriously, turn down the added child-friendly additions (Gurgi can work, if done per the novel, and with the seriousness of the LoTR Smeagol elements, but would require a good team), and keep the moments that are out and out scary (to this day, I remember how terrifying I found Maleficent turning into a dragon as a child!) and in the modern Fantasy friendly climate, it could be wonderful.
Things that would work as either remakes or sequels:
A Boy and His Dog (1975)
Legend (1985)
Labyrinth (1986)
Spaceballs (1987) - Aside, I can’t believe no one mentioned this yet, because with all the new material out there, they’d be spoiled for parody choices, and a huge chance to use new or appropriate aged originals!
That’s all off the top of my head. I can think of others that have been mentioned upthread, and there are some that deserve a good remake or sequel but have been disqualified by already having terrible ones (Highlander, The Crow (although # 2 wasn’t horrible, but the rest…) and there are some that deserve a great, well done sequel but would never be able to live up to the original’s perfect performances/casting/gestalt (The Princess Bride) so… 
I’m sure I’ll think of more later, this is mostly just thinking of movies in my collection that I’ve previously complained about on this subject, and speaking of that…
I will repeat what I said in other thread…
I am surprised they did NOT make a sequel to Con Air.
Mac and Me also ended with a “We’ll be back”.
I disagree about Galaxy Quest. It was a perfect movie, and it tied up everything with a nice, little bow.
I would love to have seen a sequel to Mystery Men.
I imagine a remake where we see the events of he first movie as they really are, not filtered though Forrest’s 74 IQ perception of the world.
That is, most of the events in the movie happened, just not like we saw them. Forrest is not a genius table tennis player, and he never goes to China. Instead he goes to a bar in Mobile and plays a Chinese dude. He plays about as good as an average Special Olympics kid. Everyone has a good laugh at the idiot.
He never makes millions in the shrimp business, though he does make a living. His business manager tells him ha makes a lot of money, but that’s just talk. he never invests in Apple. He does run across the country, but there is no coverage other than the local papers.
Needless to say, he never meets the president(s), never shows his butt to LBJ, never sends the cops to the Watergate. He thinks he does, but we find he met some local business president named Johnson.
Jenny is even worse off. She dies of aids, and so does Forrest.
It is not a heart warming movie.
Galaxy Quest had a comic book series sequel a few years ago.
I LOVE Mystery Men and cannot imagine a sequel working.
