This December, “Star Wars: The Last Jedi” will finally release, and we’ll find out what happened to Luke Skywalker after the remnants of the galactic empire crushed his resistance movement, sending him into self-imposed exile until a rebel sympathizer who may be Luke’s daughter tracked him down on the planet Ahch-To.

Until then, “Star Wars” fans can revel in tweets by Luke himself, as Mark Hamill shares obscure anecdotes and photos from the series’s rich history.

Hamill took a Cinderella path to Hollywood fame — shooting from near-total obscurity to mega-stardom with the original “Star Wars” trilogy, then rarely seen on the big screen afterward. He spent decades doing small roles, stage acting and voice-over work before returning to the series that made him famous with 2015’s blockbuster, “The Force Awakens.”

But you’d hardly notice the ups and down of fame on his Twitter feed, which Gizmodo calls “one of the few truly pure places on the Internet.” In a years-long stream of obscure anecdotes and photos, Hamill has told a behind-the-scene history of  “Star Wars” that hit the sweet spot with his hardcore fans.

It was all just totally, unabashedly nerdy.

A follower had posted a photo of Hamill’s leggings from the original 1977 film that morning. Within 10 minutes, @HamillHimself responded: “They were off-the-shelf Levi’s-Bleached w/back pockets& label razored off.”

He expanded with more pants lore that evening, unprompted. This is not unusual. If you’ve ever got a burning question about “Star Wars” — on or off set — just ask Hamill, who answers them morning, afternoon and night, often with as much fervor as his nerdiest fan.

His apparent love for sharing embarrassing memories actually predates Twitter by many years.

“With whom did you have the best relationship with during the filming of the Star Wars trilogy?” a fan asked Hamill in 2001, in a questionnaire published in Empire Magazine.

As the magazine described his response, Hamill began “throwing himself around the room in a disco frenzy,” demonstrating how he and co-star Harrison Ford would dance to bad pop music in his dressing room.

But unlike Hamill, Ford never fully embraced his inner dork.

“The minute somebody comes to the door, he’d stop dead and stand there,” Hamill said, mimicking Ford’s voice: ” ‘Yeah, okay, I’ll be down to the set in a minute.’ As soon as the door closes, it’s, ‘Get the action gain!’ ”

While Ford went on to star in hits like “Indiana Jones,” a disfiguring car accident derailed Hamill’s celebrity. For the interview, Empire Magazine introduced him as “the voice of The Joker, and Cock-Knocker in Kevin Smith’s new movie.”

Which seems totally fine with Hamill.

“I spent a large part of my life putting Star Wars behind me so I could move on,” he told the Mirror in 2015 after filmmaker George Lucas invited him to come back to Star Wars prior to Lucasfilm’s 2012 sale to Disney — a return Hamill likened to “taking out a pair of trousers from the back of the closet and discovering a $20 bill in the pocket.”

Now, on Twitter, he’s all about trousers. And wardrobe mishaps and little-known droid names, and whatever’s taking place here.

Asked and answered:

This one, too:

It doesn’t matter who you are, or what time of day it is. Mark Hamill will settle your weird argument for you.

He will finish your Yoda limerick for you, and then tell you about that one painful rehearsal with Yoda.

Transparency does have its limits. While his tweets didn’t slow down while he filmed for the new “Star Wars,” which is set to open in Dec. 15, Hamill never shared a thing about the script.

Like a young Luke Skywalker taking one last look across the Tatooine desert before leaving his home planet, Hamill’s tweets are fixed on the past.

Last weekend, heedless of any studio publicity schedule, he shared with his followers what may be the first-known photo of Luke — or rather, a young Hamill looking none-too-suave in the Tunisian desert.

And then, of course, he elaborated. On how a producer’s kid played a Jawa. And how Hamill believed, from the very beginning of the very first shoot, that “Star Wars” would become more than some dorky sci-fi thing.

“Were you thinking ‘This is gonna be my big break?’ ” a fan asked of the photo. “Or “‘Crap, it’s early, dusty and way too bright’?”

“Judging by my clueless expression, probably both,” Hamill replied. “Crew was kind but thought was ‘rubbish.’ I kept telling them: ‘We’re on a winner!’ ”

AD

And so he was, and may now be again.

Not that fame makes any difference in the fan feed.
