[UPDATE] The livestream has now ended. We didn’t get a new trailer, but Lucasfilm released a behind-the-scenes video and a new poster.

The original story is below.

The Star Wars Celebration event kicked off in London today, and one of Friday’s biggest panels is themed around the Rogue One spinoff. The event kicks off at 8 AM PT / 11 AM ET / 4 PM BST.

This will be preceded by a “panel preview” 15 minutes before the start time. You will be able to watch the panel live through the YouTube embed. Director Gareth Edwards and Lucasfilm president Kathleen Kennedy will appear on the panel to talk about the film. Some “special guests” will also appear during the event, which Lucasfilm calls a “can’t-miss” event.

In other news about Rogue One, a new trailer is expected to be released later today. For more on Star Wars Celebration, check out this roundup of everything happening at the show.

Rogue One comes out in December, with the next saga movie, Episode VIII, landing in 2017. After that, a standalone movie focusing on young Han Solo will premiere in 2018.

In other news about Rogue One, we recently learned that Darth Vader will appear in it. Additionally, a batch of new images were released, while the names and more details for the cast of characters were also shared.

Reports suggested the film’s reshoots were done to “lighten the mood,” but Lucasfilm president Kathleen Kennedy, who is a producer on Rogue One, later said the movie’s tone and story has not changed.

“There’s nothing about the story that’s changing, with a few things that we’re picking up in additional photography,” she explained. “I think that’s the most important thing, to reassure fans that it’s the movie we intended to make.”
