The trailer focuses on Rey's Jedi training under the tutelage of Luke Skywalker. "Breathe. Just, breathe. Now reach out. What do you see?" Skywalker says in voiceover while Rey navigates the Force. "Light. Darkness. A balance," she responds. "It's so much bigger," Skywalker responds.
There's also footage of space battles (including the Millenium Falcon in flight), glimpses at characters like Finn and Kylo Ren and a crushed Darth Vader mask.
The trailer concludes with the line, "I only know one truth: It's time for the Jedi to end."
During the panel, director Rian Johnson told fans that the film is still in the post-production and editing process. In addition to Johnson and Lucasfilm chief Kathleen Kennedy, the panel also featured guest appearances by Daisy Ridley – who didn't offer up any clues to her patronage, but admitted The Last Jedi goes "deeper" into her backstory – as well as Mark Hamill, John Boyega, new cast member Kelly Marie Tran (Rose, a "maintenance worker in the Resistance") and the android BB-8.
The panel also unveiled the first poster for The Last Jedi:
The Last Jedi is due out December 15th and is the third Star Wars film in the recent revival of the series. It kicked off with J.J. Abrams' Episode VII: The Force Awakens and continued in 2016 with the anthology film Rogue One, which bridged the prequel Episode III and the series' first film, 1977's Star Wars.
A film dedicated to young Han Solo, starring Alden Ehrenreich, Donald Glover, Emilia Clarke and Woody Harrelson and directed by Phil Lord and Chris Miller – arrives in 2018, with Episode IX to follow in 2019.
On Thursday, the Star Wars Celebration convention held a 40th anniversary panel, which featured director George Lucas and stars Harrison Ford, Mark Hamill, Hayden Christensen and Billy Dee Williams. The panel also included a poignant tribute to actress Carrie Fisher, who played Princess Leia in the original trilogy.
Although Fisher died prior to working on 2019's Episode IX – she had finished filming The Last Jedi prior to her December 2016 death – her brother Todd Fisher recently revealed that the Leia character will appear in the next Star Wars film via recently filmed unused footage. Producers have previously pledged not to utilize CGI technology for Episode IX.
