There are rumours of a Halo {the video game} movie, which would pretty much gazump Ringworld being filmed, since it would win in the audience recognition stakes - pity, since the setting of Halo is pretty obviously, um, “inspired” by Larry Niven.
The Callahan stories could provide the basis for a great TV series.
Funny, I see the Callahan stories more as a TV serie (cable, of course) than a movie.
As mentioned in this previous thread, I’d like to see **The Kraken Wakes ** (by John Wyndham) - particularly the scene of the sea tanks’ attack on Escondido.
From a directorial standpoint, I would want to see Octavia Butler’s Wildseed. The two main characters are a spirit that jumps from body to body and a shapechanger. I would love to see a director pull off keeping several actors of different genders and ethnic background playing the same character and doing it convincingly.
I would also nominated Joan Vinge’s The Snow Queen, because of the wonderful characters, and wouldn’t rely too heavily on special effects.
And I’m going to cast a “NO” vote for Rendevous with Rama. It was a great book, but I can’t see it translating well to film, at least if they stay true to the novel.
At least you spelled it right.
A lot of my interest comes from the original guy, the one who made those characters out of robots.
He fascinated me.
I swear that your post wasn’t there when I posted mine. Goes to prove that weird minds post alike 
couldn’t agree more. I thought this book would make a very good movie.
maybe one day.
And I agree–that Jeff Daniels would make a very good Harry the Mailman!
Oh, I forgot to mention Dirk Gently’s Holistic Detective Agency. Since it was clearly based on a couple of television scripts for some British program no one has ever heard of 
it shouldn’t be too hard to adapt. If the Hitchhiker’s movie goes well, perhaps…

Dan Simmons’ Hyperion/Endymion saga as a series of movies.
Robert Charles Wilson’s The Harvest. Not much sci-fi but great human drama.
Stephen King’s Dark Tower. Okay, that’s stretching the sci-fi definition, but what the hell.
Crap! Forget Robinson’s Mars trilogy.
Each book (Red, Green, & Blue) could be a year-long TV series.
Hah! I thought your ame was from The Man Who Never Missed! I was right!
Any of those books would make for good eye candy funky cyber-movies. Maybe The 97th Step? Haven’t read them for years.
If I can stray into fantasy, I’d like A Song For Arbonne, and Sabriel. Lots of room for cool special effects in Sabriel- Charter magic and zombies and the Mogget. What the heck- do Lirael and Abhorsen, too.
The 97th step would be fun too. you are right, it would be eye candy. It is “light” sci-fi. None-the-less, I’m disappointed that Steve Perry doesn’t seem to be writing original stuff anymore (mostly Star Wars and Net Force stuff.)
I read Sabriel when I was in the hospital two summers ago. It was a tough read for me, but that was because I was on some major pain medicine and couldn’t think well. I may have to go back and read it again. I haven’t read the other two yet.
The danger there is that DNA wrote the screenplay for Hitchhiker’s. We’re unlikely to get one as good for Gently.
I read one recently by a lesser known author, which I really enjoyed. A single book, not a series. Mainline – Deborah Christian.
Had too much going on to fit into a 2 hour movie, but when I was reading it, I was picturing it as a mini-series (and thinking it would make a good one). Including planning it out in my head how many hours it would need, and where the break points would be for each segment. Anybody else read this one?
Did you know Asimov later wrote a story about a director making a CGI version of this story?
I would like to see more William Gibson and Phillip K Dick movies done. If they were done properly.
If the guy who made Donnie Darko or the director of Memento did a Pillip K Dick book it would be really good. (maybe)
Oh and Gibson with Keanu Reeves would be nice to see.
Yeah, but the screenplay for Gently pretty much writes itself, seeing as how it was more or less adapted from two Dr. Who screenplays that Adams wrote.
It could be done, and in the style of Adams, by the right screenwriter. Whether someone could turn it into a credible movie, and whether the opportunity could even exist is a question for the future.

I certainly wouldn’t complain about any of the three, if they’re done well, but the gender-bending in LHoD would be tough. We’d need a full cast of very androgynous actors, at least one of whom has to come into kemmer during the movie.
I’m sure he did know, since he refers to the characters as squares and triangles. They’re never described as such in The Gods Themselves, only in “Gold” (where the director comments that they’re not described in the book, so he was free to interpret them).
