An inane topic a co-worker and I were discussing…
I’d kind of like to see a Resident Evil/Tomb Raider team-up. Let’s see, Alice and Lara kick ass, fall in love, and make out. It’d make MILLIONS! 
Spider-Man / Superman
Batman vs. Freddy vs. Jason
Honey! I Shrunk the Spy Kids
And then, hopefully, I Stepped On Them.
…
Okay, okay. How about…
The Incredibles / Fantastic Four?
(The degree of similarity in powers between those teams already, it might be kind of interesting to see them face to face. 
)
On a different note… I’d like to see a movie with Eddie Murphy, Robin Williams, and Mike Myers. Only Eddie, Robin, and Mike. Playing all characters. Hell, you wouldn’t even need extras.
A movie mega-crossover of all the Marvel characters put to film in the last 9 years.
There is a 1 in 28 chance that such a movie wouldn’t suck.
Well, if they get Tia Carerre as their leashed sex slave… okay.
I’d like to see a Predator v. Aliens that didn’t suck. Barring that, Knight Rider meets Airwolf meets Street Hawk, with a cameo by Blue Thunder.
And the sequel could star the survivors going up against the Dukes of Hazzard and Viper!
I really, really want to see an Infinity Gauntlet movie or something similar.
Rocky vs. Rambo
Rambo vs…Terminator.
Or Rambo vs. Predator, maybe?
A movie with all the near-forgotten Golden Age comic heroes, set in WWII.
The Vega Brothers, the prequel to Reservoir Dogs and Pulp Fiction that Tarantino talked about making for years (and then got sidetracked to do other projects). Of course it would have to star Michael Madsen and John Travolta.
A movie with Jackie Chan, Chow-Yun Fat, and Jet Li as a team of heroes (or perhaps one of them as the villain). This would have to be a Hong Kong production to be good, perhaps with John Woo signed on as director to recapture the magic of his earlier HK films.
Agent Sands, Johnny Depp’s character from Once Upon A Time In Mexico, teaming up with Elle Driver, Daryl Hannah’s character from Kill Bill, playing two blind assassins out for revenge.
Oh, and how much less would those Matrix sequels have sucked if Matrix: Revolutions ended like this:
After the scene of the robots carrying away Neo’s dead body, splayed out Christ-like, we fade away to a virtual reality chamber. NEO (Keanu Reeves) is in a comfy-looking chair with a virtual reality helmet on his head, which he lifts off. He looks around the room, disoriented, and sees the staff going about their business. It is clear he is back in the normal world, and that the last three movies (or at least the last two) were a dream, a fantasy, a simulation.
NEO: Whoaaaa.
Pan to the next chair, occupied by DOUGLAS QUADE (Arnold Schwarzenegger), who is holding his virtual reality helmet in his lap.
QUADE: You think that’s something? I just went to Mars!
And then we link that up to the final scene in BRAZIL!
My dream team (originally meant for TV but could also be in a movie) Mulder, Scully & Dale Cooper.
Rocky would win, because in Sly’s own words, “Rambo is a pussy.”
Joshua from Lethal Weapon and Alan Rickman’s in Die Hard. They’d kick some serious ass.
Better yet, Joshua and Al Schwerengen from Deadwood. Yeah, sociopaths are fun!
Yeah ! Since it would give us a John McLain/Martin Riggs team-up (maybe throw in Shaft in there also)
Yeah, John McLain teams up with Martin Riggs and Roger Murtaugh! The bad guys would so get their asses kicked while the good guys trade wisecracks! How did nobody think of this before?
Any other cop heroes we could add? Maybe Frank Drebin? Nah, Riggs would break his arms.
Or Mulder and Scully could go to Hannibal Lecter, the FBI’s number one go-to-guy when they’re clueless, for help.
I’d LOVE to see John McClane forced into an uneasy alliance with the ass-kicking hero with NO sense of humor, Jack Bauer (the hero of 24, played by Kiefer Sutherland). Bauer is one of the only action heroes I can think of who could take out McClane or Martin Riggs if he had to. All three are tough, but Bauer definitely has the stone-cold killer instinct that the other, more “likeable” heroes seem to lack.
Of course, seeing Bauer face off against Hans Gruber (Alan Rickman’s brilliant Die Hard villain, somehow back from the dead) would really complete the package.
I would LOVE to see a superhero period piece with an epic backdrop of World War II, but I think too large a roster would never happen due to licensing nightmares. Frankly, I think this would be the best era for a Captain America movie, but doing the Justice Society or All-Star Squadron as a live-action film might be asking a bit much from Hollywood.
The comic books that I think would make good movies or TV shows are mostly continuity-free, and could stand on their own without any mentions of any other characters or events. Furthermore, they wouldn’t depend too much on outlandish Spandex costumes or hard-to-capture-with-CGI super powers. Any of the following could easily overcome the “comics are for geeks” stigma and catch on with mainstream audiences.
Grendel (“Devil By the Deed,” the Hunter Rose story, would make a perfect movie)
Starman
The Question
Sleeper (this would be best as an HBO miniseries)
Sandman Mystery Theatre (another character best set in the '30s and '40s)
Phantom Lady
The Shade (the immortal, amoral antihero from Starman)
Gambit (as a dashing adventurer and thief in New Orleans, with no tie-ins at all to the X-Men)
Moon Knight
Preacher (only as an HBO miniseries, or something with as little censorship as possible)
