There will be sequels to both Star Trek and X-Men Origins: Wolverine. Not only are these now officially greenlit, but they’re also what we call “likely sequels” prior to their certainty — meaning we all saw them coming way before Paramount and Fox, respectively, announced them. However, it’s not necessarily a given that a successful movie will always spawn a follow-up. For example, box office record-holder Titanic could never become a franchise.

Of course, people will always joke about the possibilities for a Titanic sequel, and that kind of humor is what makes the Twitter meme #unlikelysequels so entertaining. Unfortunately, 140 characters allows for little more than a proposed sequel title (and yes, “Titanic 2: Jack’s Back” is among them), so we have decided to expand on ten favorites by providing the synopsis and, for some, casting suggestions.

E.T. 2: Glowing Death Finger (Tweeted by @MeganPanda)

Either @MeganPanda coincidentally came up with this title on her own, or she pilfered it from a seven-year-old list on BBspot.com. But it doesn’t matter where the title comes from; it’s still a great idea. With Steven Spielberg now making movies about scary aliens (War of the Worlds; Indiana Jones and the Kingdom of the Crystal Skull) rather than movies about lovable aliens (Close Encounters of the Third Kind; E.T.: The Extra-Terrestrial; *batteries not included), it’s fitting that an E.T. sequel would be on the darker side. Here’s the premise: 25 years after E.T. went home, his planet faces an obesity epidemic, thanks to the little guy’s introduction of beer and peanut-butter candies to the rest of his world. Angry elders from the planet blame Earth and so they attack. Can the grown-up Elliott and Gertie (Henry Thomas and Drew Barrymore) save us from the glowing death fingers?

9th Mile (Tweeted by @Eloi_Casali)

The title for this sequel to 8 Mile could also be “9 Mile,” we think, but @Eloi_Casali is probably taking into consideration that Jimmy (Eminem) has gone that next mile, at least figuratively. And what does he find there? Here’s the short subtitle provided in the Tweet: “how eminem lost his talent after becoming a celeb.” Of course, 8 Mile wasn’t exactly about his life, specifically or officially, so the rapper shouldn’t have a problem with making a sequel that also isn’t necessarily about his own decline as a rapper. It would simply be about Jimmy’s shot to stardom, loss of talent (according to @Eloi_Casali, anyway), subsequent four-year hiatus and ultimate comeback. Presumably, Eminem will one day be at the position in his career where he will act in anything, and that should be when Curtis Hanson comes along with this comeback opportunity.

Batman Ends (Tweeted by @mathias_simon)

A simple response to the title Batman Begins, this unlikely sequel should have been The Dark Knight. As in, that film should have been titled Batman Ends and the franchise should have let the thing stop at two great films. Part of this idea is in agreement with Kyle Buchanan’s rant against trilogies over at Movieline, but since the second film already came and went, and because the third film is happening (does that make this any less of an “unlikely sequel”?), Batman Ends should be the title for that installment and Warner Bros. should still close the series while it’s ahead. The sequel, inspired by the “Batman R.I.P.” comics storyline, will pit Batman against Dr. Simon Hurt and his Black Glove organization, and it will conclude with the Caped Crusader’s death via helicopter crash. Obviously, just as in the comics, it would still technically be possible for the character to return for future films, so Warners shouldn’t worry too much about allowing such a premise.

Memento 2 (Tweeted by @Pezt)

While we’re on the topic of Christopher Nolan movies, here’s a popular selection for the meme: Memento (best title, Tweeted by @DougPiranha: “Memento 2: Mementos - The Fresh Maker”). In @Pezt’s Tweet, though, he finds enough room for a short description of the plot: “his short-term memory loss causes him to go through it all yet again…” Funny, sure, but not completely unlikely, is it? Think of all the sequels that have basically just rehashed the plot of the first film, with some slightly different events. Memento 2 would at least be appropriately repetitive/redundant, with the main difference being that Leonard (Guy Pearce) would encounter a new love interest and a new scapegoat. A similar idea consistently being suggested is a Groundhog Day sequel. According to Twitter member @alun, the title of that sequel would also be the same: “well what else would you call a sequel to Groundhog Day?”

Ocean’s 10: The Younger Years (Tweeted by @Neef_Dave)

This fits more with a to-be-made topic called #unlikelyprequels, but prequels are kind of considered sequels, so here it’s included. The simple premise: an origin story of Danny Ocean and his crime-caper buddies, set when they were much, much younger. Obviously, despite the fact that Hollywood is always trying to go younger (and hotter, hipper, etc.) with its franchises, this is one series that would not benefit at all from replacing George Clooney, Brad Pitt and the rest with Zac Efron, Michael Cera and other similarly fresh faces. Actually, it does kind of sound like a good idea, now that we’ve written it.

The Passion of the Christ 2: The New Batch (Tweeted by @AlexJThomas)

There are a lot of Passion of the Christ sequel ideas, but most have to do with the resurrection, zombie-style, of Jesus. That’s why we like this title the best, because it instead references the Gremlin-like multiplication of Christians following Jesus’ crucifixion, thanks to the apostles. Like Gremlins 2: The New Batch, this sequel will be better than the original, both because it will be less violent and more self-parody. One of the apostles will be brainy and sound like Tony Randall, while another will be made of electricity, while still another will become a spider-like creature who traps potential converts in his web.

Amadeus 2: The Emperor Strikes Bach (Tweeted by @tprclassical)

Technically, this classical biopic would be a prequel, as Bach came before Mozart. But what a great pun! Actually, @tprclassical may be merely using the Bach name for the pun, and this will actually be a spin-off centered primarily on Emperor Joseph II (the Tweet does reference the character’s “too many notes” line). And that’s fine by us, because we’d love a Jeffrey Jones comeback. Either way, though, that title is terrific, and we wish it could be used for some sort of follow-up.

No Country for Old Men Origins: Anton Chigurh, the Teen Years (Tweeted by @MiramaxFilms)

That’s right, even the distributors are getting in on this. But does this mean Miramax would definitely never make an Anton Chigurh prequel? Such a sad thought, even if it is indeed unlikely that such a thing would happen. Honestly, though, we’re not huge fans of the villain origin movies, which always water down, or otherwise ruin, the character (see the Star Wars prequels; Hannibal Rising, etc.). We have previously proposed that Anton Chigurh get a spin-off in another list, and we even warned against it being an origin film (“While Hollywood might prefer to be consistent by ruining the character’s mystique with a prequel explaining Anton Chigurh’s background…”). However, now that we know Miramax views such a prequel as unlikely, we actually want it to happen. Matthew McNulty, who is terrific as Luis Bunuel in Little Ashes, would be great as the teenaged serial killer-to-be (though costar Robert Pattinson sports Chigurh’s hairdo in the same film, rather well, too).

Ferris Bueller’s Laid Off (Tweeted by @JayToTheMe)

There has long been talk of a sequel to Ferris Bueller’s Day Off, which would have the titular character (played by Matthew Broderick) playing hooky from work. But in this economy, @JayToTheMe has the more likely idea for a sequel, in which Ferris is let go from whatever job he has, turns lemons into lemonade, and makes the best of his situation. It would have that same kind of “enjoy life while you can” message of the original, because even though he’s unfortunately now unemployed, he manages to hack into his old employer’s HR files and give himself a better severance package. Then, he and Sloane and Cameron (Mia Sara and Alan Ruck) reunite for a cross-country road trip. A similar premise actually happened to a friend of ours (without the illegal hacking, of course), so it’s not entirely an unlikely plot. The only difficult thing is figuring out how Ed Rooney (more comeback opps for Jeffrey Jones!) would figure into the story — because he’d just have to.

Seven Samurai and a Little Lady (Tweeted by @blurryleg)

There are too many ideas being submitted to this meme that aren’t so much sequels as they are combinations of two or more films (we do appreciate the Vs. ideas, though, especially Forrest Gump vs. Rain Man – Tweeted by @benpobjie). Yet Seven Samurai and a Little Lady strikes a chord with us, because it’s the most perfectly ridiculous mash-up of a classic film and a lame Hollywood comedy. And who wouldn’t want to see the story of a band of samurai warriors who are suddenly stuck taking care of a precocious little girl? Too bad none of the original samurai from Kurosawa’s film are alive, but if the Weinstein Co. ever comes through with their Seven Samurai remake, and it’s a hit, might we suggest that Harvey Weinstein buy the rights to @blurryleg’s idea? Because as long as someone’s going to go so far as to produce an initial redo, why not go the extra yard and turn it into an hilarious franchise?
