I had a similar idea a while back, to do an action/sci-fi version of The Magnificent Seven, but to cast Bruce Campbell, Christopher Walken, Steve Buscemi, Michael Madsen, Jason Statham, Vince Vaughn, and William Shatner.
“Wish there were.” It’s the subjunctive mood.
Oh, I love that album!
A good movie about invention. A movie about someone who takes an idea from a bare concept to realization. I don’t care if the movie is fictional, as long as it doesn’t focus on a love interest or an irrelevant ‘evil corporation’ subplot or something. I would watch it even if I’d never heard of the thing being invented, as long as the plot centers on problem-solving and the application of intellect.
There are any number of specific science fiction stories that I would love to see get a good screen treatment, but I have the sinking realization that that’s the exact wrong way to go. Books are books and movies are movies, and when you try to mix media you end up with unreadable trash or unwatchable dreck. 2001, as much as I loved it in both of its incarnations, wasn’t an approachable film: You had to intuit vital parts of the beginning and the end with no help whatsoever from the people who were supposed to be telling the story. It made sense if you had read the novel, in fact it is a very good movie if you have the book to fall back on for plot comprehension, but without that it’s a bunch of guys in ape suits screaming at a black rock and a bad acid trip.
(The really sad thing is that 2001 the movie was co-written by Clarke himself, who should have known better.)
So I suppose I’ll just say that someone, anyone writing screenplays now really needs to get in touch with the modern SF field and create a new screenplay (as opposed to a book or short story mutilated into a screenplay) that advances the field.
I’d like to see the James Bond series become a darker, more serious plot-driven thriller instead of the campy, formulaic popcorn films they have become. Something more along the lines of the original books. I think Bond should also be done as a period piece set during the cold war in the 1960’s.
Another idea I think could be interesting if done right would be for a story with two main characters to be made into two movies released simultaneously telling the same story from the points of view of each lead character. For example, you could take a romantic comedy and one movie would be from the man’s point of view and the other from the woman’s. The two films would share some common scenes (perhaps edited differently) when they’re together and also have their own scenes when apart.
I’d like to see a movie where Aliens square off against Predators, that’d kickass for sure. Wouldn’t it? 
This is impossible, but I’d like all movies to be cast with the best actor for the role, not just the best looking, youngest, most politically correct, etc. So many movies I’ve gone to, the premise was good, the actors were good looking but just didn’t sell the movie. But this will never happen.
Something similar to this was done in the two-part film “Divorce: His” and “Divorce: Hers.” The same story was told from the differing viewpoints of a man and a woman (played by Richard Burton and Elizabeth Taylor) whose marriage is dissolving. It wasn’t a romantic comedy, though. Very tedious stuff, but the concept was interesting.
Second that.
After that…
•A World War II movie…set in an alternate 1947, where the war is still raging, growing ever closer to an apocalyptic finish. Lots of crazy Axis weapon designs,™ etc.
•Peter Jackson’s Alexander Nevsky.
•A biopic of Nietzsche. (I’m thinking Gary Oldman in the title role)
•Bungie Pictures presents: Marathon.
For what it’s worth, Halo is in the works.
I liked to see a full Hollywood version of the Wright brothers story. I read a book about their invention of the airplane and competition between various groups and it seemed like it would make a pretty good movie. Most people don’t know that even after they flew the first airplane they got virtually zero publicity for several years and continued to work in secrecy for 3 more years building better and better planes. After other people including the French started showing off their airplanes as the first, the Wright brothers were forced to give a public demonstration of theirs and blew everyone else out of the water. Even then, it took many years to convince authorities including the Smithsonian to grant them the status of being the first.
Rob Schneider IS Master Chief in a performance all the critics say “must be seen to be believed”. Co-starring Alec Baldwin as Gordon Freeman…for about fifteen seconds, until he realizes he’s in the wrong movie and leaves.
I’d love to see a Christopher Guest-style “mockumentary” of the Soccer Mom culture.
My town is a breeding ground for this culture, and I like to watch people interact that are part of this way of life and mentally play out dramas that would suit a Guest movie.
There has to be a scene with Walkin reading Dr. Suess to pre-school children.
Oh, and a special cameo by Jack Nicholson.
I wish they’d make more movies with “normal” looking people. People who haven’t had tons of facial surgery. An example: “Welcome to the Dollhouse” had kids and adults that you could actually know, not ones that live in Beverly Hills. I guess the “Creepy Lookin’ Mofos” could count. 
The next best thing: Soccer Moms, a play by David Starkey. I saw the production reviewed in the link; pretty funny stuff.
An American animated Porn cartoon similar in quality to the best Japanese hentai.
Red Vs. Blue: The Movie
Live Action Sailor Moon: The Movie
I saw a real neat preview of a movie awhile back called (I think) Zu Warrior(s). As far as I can tell it never came out on DVD. It was a combination of a Crouching Tiger style Martial Arts movie and a fantasy epic. I want to see that.
I’d really love to see Schlock Mercenary become a feature film… or a TV series, I don’t know which would be better. I also can’t decide if it should be animated, CG, or live-action…
I’ve long wanted a movie based on the game Sky Galleons of Mars. Set in 1889, with flying gunships, martian skyships, arid deserts and dense, dinosaur-filled jungles…
But…I want the movie to be good. So it would have to have an actual plot. It would have to be well acted. The special effects would have to be top-notch. And the conflict would have to have some meaning, thus evoking actual drama, rather than the phony crap that usually passes for entertainment in mainstream cinema.
I’d also like to see a movie version of Patrick O’Brian’s books, made by someone who understood them. Sure, there was “Master and Commander: The Far Side of the World.” But that movie’s so confused they couldn’t even figure out which book they were making a movie of. I want a movie of the first book, done right, with attention paid to who the characters actually are.
I’d also like to see Watchmen, done right.
Have you seen the trilogy, Un couple épatant, Cavale, and Après la vie? They’re not American films, of course, but they’re just the thing you’re asking for.
Also, check out the Trois couleurs: Rouge, Bleu, Bialy films by Kieslowski. They’re somewhat close to what you are describing (and I love how they’re tied up in the end.)
Stranger
A movie in which an intelligent, skeptical person living in our completely non-magical world finds an actual magical item and attempts to figure out how to deal with it, how to convince people it’s real, etc.
