It’s less than three weeks until the eighth instalment of the Star Wars saga hits the big screen, and Luke Skywalker himself, Mark Hamill is asking fans not to reveal spoilers after they see The Last Jedi.

Fans have been eagerly awaiting the film, since the very first trailer debuted back in April. Since then, we’ve been pulling apart every quote and frame from that trailer, and from the full one that was released just last month, as well as dissecting all of the behind-the-scenes action and titbits from cast and crew, all in the hopes of working out what Rian Johnson’s film is all about.

All the answers will be revealed when December 15th comes, and getting in an early warning, Hamill is asking fans to keep their thoughts to themselves for as long as possible, so as not to ruin the plot for others.

In a recent tweet from the actor, he includes a cartoon showing a man marking off the days on his calendar when a woman behind him asked “Counting down to Christmas?” to which he replies, “No. Star Wars.”

While the cartoon is comical, Hamill posted it with the inclusion of a heartening message, “Let me take this opportunity to personally ask you to keep all that happens in #TheLastJedi a secret for as long as is humanly possible.”

Hamill is as much a fan as anybody at heart, so you know his message is genuine. He wants all audiences to be able to experience the film with a fresh pair of eyes, and for those who see earlier showings not to throw around plot points in an “I’ve already seen it!” way, ruining the film for others simply for bragging rights.

Once the critics and press screenings begin in a couple of weeks, fans should be aware that they will be venturing into social media at their own risks, but hopefully both media and fans will hear Hamill’s warning and take heed.

If you don’t, you’ll be disappointing Mark Hamill. And he’ll know. He’ll sense the disturbance in the force.

Spoil at your own risk!
