I've long wanted Terry Pratchett's Discworld to be made into a series. I used to think it wouldn't be possible because of how much the humour relies on the narrator, but after seeing the (IMO successful) Netflix adaptation of A Series of Unfortunate Events, I think it is possible.

Old Man's War! Pretty green people fighting aliens! What's not to like?

well it used to be wheel of time.

No one has mentioned The Culture?

There really wouldn't be much to update because a good chunk of it is still modern. Not only that, but Banks really fucked with gender, ideology, and civil rights in a way that is still incredibly relevant in 2023.

I also really want someone to try to portray Fwi-Song from Consider Phlebas.

Well, I have some good news for you!

Stephen Colbert to Produce ‘Chronicles of Amber’ TV Series Adaptation.

The Kingkiller Chronicle

Abhorsen / Old Kingdom series.

I don't like reading but I breezed through the first three books. I think all the dark, necromancy type stuff would be generally well received. The gates of the afterlife also sound really cool to be put in a visual form.

The Lies of Locke Lamora would make a fantastic show/movie if done well, and I feel like the vast majority of it is pretty screen-friendly. Basically just some minor cgi for the scorpion-hawk and Falselight and you're good.

"Chasm City" by Alastair Reynolds. It's a standalone novel in a much bigger Revelation Space series. But the plot of this book is quite independent of the series, you don't need to know the lore to understand it. I think it is very well suited for a movie or a short series.

The setting is hard SciFi, very detailed, but not too crazy.

Still waiting for a Mistborn adaptation.

Piers Anthony's Incarnations of Immortality series of books. The first book alone, where a guy who was about to unalive himself accidentally kills death instead as he walks in the door to take his soul, would make an awesome series. Each book takes on a different aspect of Immortality (Death, War, Time, Nature, etc.) and how they overcome Satan by not being used for ultimate evil.

That last sentence may seem religion-forward but the author, Piers Anthony, is not a religious writer by any means. Another series of his, Bio of a Space Tyrant, could be an ultra gritty R rated Sci-fi epic with the right director.

Brandon Sanderson's Cosmere universe would be fantastic. The last thing I remember hearing was that he was working on a script for a Mistborn movie. I would've preferred a TV-show, but he feels it would work better as a movie, and I trust his judgement.

I'd absolutely love a faithful adaptation of SnowCrash by Neil Stephonson to a TV series, don't think a movie would be doable, unless they did a trilogy or something.

The ministry for the future by Kim Stanley Robinson. And moreso after the Texan republicans are trying to keep climate science out of classrooms!

I have often thought about dragonriders of pern as a movie. I am not sure thread really would show well. The books really emphasize people's fear of thread. But I don’t see anything visual about it that would really inspire that fear on the screen. Even while reading, I often felt the fear level was unrealistic. And a lot of peoples motivations were based on that fear. Now a great writer might be able to adjust things to work aroundvthat, but it seems tough.

Hyperion Cantos (Dan Simmons)

Any of the Xeelee series (Stephen Baxter)

Quantum Magician series (Derek Künsken)

Project hail Mary is my favorite literature I've read in the last few years.

I would love to see it done justice with a movie done right.

Firefly looks good.

I always wonder why sci-fi gets mixed in with fantasy so much? It's always a pain to find decent movie/show or a book because these categories are treated as the same thing.

In my mind they are trivial to separate and I struggle to think of a single book or a film/show that even comes close to crossing over.

I enjoy quality writing in either genre, but as I get older I gravitate towards sci-fi because most fantasy seems to be written for younger audience with some great exceptions like Chronicles of Amber or Witcher.

And just to stay on topic, I nominate Asprin's Myth Adventures.

I read some Halo books that seemed like they'd make for great TV.

More "The Expanse" would be awesome.

The Caves of Steel quadrilogy. Especially now that we're on the eve of AI mates, this one would be fitting for the times.

I'd love to see the Foundation and the Robot series of Asimov.

As single movie, Asimov's End of Eternity would be great.

Drangonlance could be as epic as The Lord of the Rings. Yes, really.

Warhammer 40k - Horus Heresy, live action, to the books. Then Eisenhorn eventually.
