'Star Wars: Last Jedi' trailer debuts during 'Monday Night Football'

'Star Wars: The Last Jedi' trailer reveals three theories

The newest trailer for 'Star Wars: The Last Jedi' has been released. We take a look at some of the best theories fans have come up with about the next installment in the 'Star Wars' franchise.

The "Star Wars: The Last Jedi" trailer debuted during the Monday Night Football halftime in dramatic fashion.

Fireworks flashed as Stormtroopers marched onto Chicago's Soldier Field as the preview played onscreen.

New and familiar characters from the Star Wars universe were featured in the trailer. The clip opens with voiceover from Adam Driver's Kylo Ren saying, "When I found you, I saw raw, untamed power — and beyond that, something truly special." Then Rey (Daisy Ridley) is shown wielding her light saber and questioning her destiny as Luke Skywalker (Mark Hamill) observes, "I've seen this raw strength only once before. It didn't scare me enough then. It does now."

John Boyega, Oscar Isaac and Carrie Fisher also appear in the trailer, as does Chewbacca and a new bird-like creature known as a Porg.

"The Last Jedi" is the latest installment in the Star Wars franchise since the Disney reboot that began with 2015's "The Force Awakens." It's set to hit theaters Dec. 15.
