Where the hell is Luke Skywalker?
That's been the burning question on Star Wars devotees' minds since a week of aggressive marketing for Star Wars: The Force Awakens culminated with the premiere of the film's final trailer before its December release. Conspicuously absent from Disney's marketing blitz is, strangely, Mark Hamill's Luke Skywalker, the man at the center of the entire fictional universe. His appearance in the trailer was limited to his black-gloved hand (footage we saw in the first official teaser for the film last year). He wasn't on the movie's official poster. Even the new Force Awakens toy line has an updated Han Solo, but not Luke.
So what's going on here? Often, omissions prior to the release of a highly anticipated film are deliberately designed to obscure a specific plot twist (case in point: Liam Neeson was officially cast as "Ducard" in 2005's Batman Begins, with Ken Watanabe as Ra's Al Ghul, despite the fact that the latter turns out to be merely a decoy). Since Disney has done a scarily good job of keeping the plot of the new film under wraps, it's likely that there's some sort of storytelling twist tied to Luke that will help set up the new trilogy.
And now, some theories:
Luke Skywalker Has Turned to the Dark Side
Yes, this is somewhat blasphemous and a plot twist right out of Go Set a Watchmen (Atticus Finch is now racist? But...why?), but hear me out.
Prior to the announcement of the The Force Awakens, there was an entire ecosystem of media dedicated to the Star Wars universe that was considered generally-kind-of-sort-of cannon. Dubbed 'The Expanded Universe' by fans, it encompasses comics, books, video games, and even cartoons like The Clone Wars.
Disney ditched this when it announced The Force Awakens, essentially declaring decades of ancillary storytelling, but it's hard to imagine that a filmmaker like J.J. Abrams would entirely jettison an "almost 30-year experiment in collective worldbuilding," as Slate's Jamelle Bouie puts it. And here's where, maybe, we get the roots of Evil Luke, according to Bouie:
There’s Timothy Zahn’s tale of a resurgent Empire led by Grand Admiral Thrawn; the fun and fast-paced adventures of Rogue Squadron; the ancient history of Knights of the Old Republic. And there’s the tragedy of Jacen and Jaina Solo, twin children of Han and Leia. Both become Jedi. Both fight to defend the galaxy against a terrible invader. But Jacen falls to the Dark Side of the Force, to become Darth Caedus, the grandson of Darth Vader.
The story of Skywalker twins who split between darkness and light is potent and painful—and it’s the first thing I thought of when I saw a trailer featuring a mournful Leia and no sign of Luke whatsoever.
This might actually make sense. What other Force-sensitive master could possibly mentor Adam Driver's lightsaber-wielding Kylo Ren, the villain of the new film? Is it possible that, between Darth Vader's Return of the Jedi denouncement of the Sith and the seeming failed state that is the New Republic, that Luke might actually turn to the Dark Side after decades of disappointment? It would also follow the arc of Anakin Skywalker.
Maybe the Force — that universal field that "calls" to people, per the new trailer — is actually more dark than light, a corrupting force for which the Jedi were once a worthy bulwark? It would help explain why Daisy Ridley has no real knowledge of the Jedi or the Force in the new trailer: perhaps Skywalker squirreled himself away before fulfilling the Sith 'Rule of Two' with Ren.
Plausibility: Not very! It would be a real shot in the gut to fans if this was the case, and I'm not sure J.J. Abrams, despite his Lost and Star Trek bona fides, has the balls to mess with a franchise like this. But who knows! Life is long and we're all hurtling towards death anyway.Luke Is Captive
Luke is missing, but not willingly: Perhaps KyloRen— an old apprentice of the late Vader in line with the Rule of Two, maybe? — snatched his mentor's killer and hid him away to extract more secrets of the Force from the actual Chosen One. It stands to reason that even though Anakin Skywalker picked up a vast knowledge of the Force through his training at the pre-Empire Jedi Temple, Yoda probably knows a few things that even Vader doesn't — and passed them on to Luke. After all, there's a long period between The Empire Strikes Back and Return of the Jedi where Luke goes to Jedi Knight boot camp.
Anyway, having Luke go missing isn't just a great marketing tool, but a fantastic plot device. What else would bring an aging Han and Leia together with scrappy upstarts Finn (John Boyega) and Rey (Daisy Ridley) than a search for the only character who really matters worth a damn in this entire galaxy?
Plausibility: Actually kind of plausible, sort of! There are rumors suggesting that Luke's been missing for at least a decade when the film opens. Then again, those rumors suggest a simpler, more elegant explanation...Luke Skywalker Is Yoda
My last theory is that Luke will die in The Force Awakens, but I don't even want to go there. This was already a lot to swallow. Here's the new The Force Awakens trailer to make up for it.

Three theories on the Jedi's conspicuous absence from the Star Wars: The Force Awakens hype.
