(AP) -- Fans at the Disney expo D23 were treated to a behind-the-scenes featurette from the upcoming "Star Wars: The Last Jedi" Saturday but no full trailer for the highly anticipated space epic.

The footage showed the late Carrie Fisher telling the camera that the film is about family, which is what's so powerful about it.

A sequel to "The Force Awakens" written and directed by Rian Johnson, "Star Wars: The Last Jedi" picks up with Daisy Ridley's Rey and Mark Hamill's Luke Skywalker on that remote cliff.

Johnson, Ridley, Hamill, John Boyega, Laura Dern, Gwendoline Christie, Kelly Marie Tran and Benicio Del Toro were on site to hype the film and their Star Wars fandom.

"The Last Jedi" blasts into theaters Dec. 15, or, as Disney Chairman Alan Horn said, 153 days from now.
