I’d love to see another Firefly movie.
Dirk Pitt™ should have been a movie series long ago, but Cussler is… unsuited to Hollywood and insists on maintaining a high level of control that both damages the film development and causes endless quasi-legal headaches. He simply can’t stand to see a director get anything “wrong” and throws a huge fit. I’d wager that between this history and the unlikelihood that he’ll ever sign another movie contract (even with generous concessions his way), two and only two Pitt movies, one awful and one pretty meh, are all we’ll ever see.
It is, however, long overdue for a few good Travis McGees, and I quietly send supporting vibes to Leonardo DiCaprio at every opportunity.
They made a sequel, with the same director and everything. 
The Big Lebowski almost sounded as if they were planning on a sequel, given how Sam Elliot was mentioning at the end that a little Lebowski was on the way.
I’d love seeing more of The Dude.
District 9. Although if Elysium is indicative of what might happen, perhaps not.

Agreed. For me, Rocketeer is the “best” comicbook movie ever made. A sequel couldn’t possibly do it justice.
The Rocke-who?
I want the Riddick sequels that actually continue the story from Chronicles of Riddick. The new one did continue it(in the director’s cut), but I want the full sequels.
I always thought a sequel of Deliverance could be fun.
“Deliverance II-This Time it’s Personal”. (Actually it was pretty personal the first time.)
A sequel to one of the biggest bombs of all time? What are you? Some sort of Communist??
I would like a Casablanca sequel --and I had this sudden crazy idea that Doug Stanhope should be cast as Rick.
Even as a Coen fan, and lover of the absurd, and admirer of all three leads… that movie leaves me totally cold. I do not get the love.
Van Helsing.

Pulp Fiction 2: The Many Travails and Wanderings of Jules
Push. It was supposed to be the first movie in a series and it ended on a cliffhanger. But it did poorly in the box office and the sequels never got made. (I think I once counted and found that Chris Evans has been in eleven different movies based on comic books.)
Megamind. Kinda bombed at the Box Office, and competition from the similarly-themed Despicable Me didn’t help, which is a pity, since it was a decent animated movie.
** Live. Die. Repeat-** The Tom Cruise vehicle that shouldn’t have bombed. Even the execrably bland original title doesn’t explain why this movie wasn’t a big hit. Give it another chance with the right title, I say.
Se7en- No, seriously. Those were two excellent characters. Of course, in the new movie (“Ei8ht”? or maybe make it a countdown for a heptalogy and call it “6ix”?) neither would be in the police anymore, but thay can still team up to get a new convoluted serial killer.
The Last Starfighter. And it should be called The Next Starfighter.
Apparently the rights owner, Jonathan Betuel, will not let anyone near it.
I always thought a sequel to The League of Extraordinary Gentlemen would do well.
