The trailer for the newest Star Wars movie was released on Friday during the Star Wars Celebration in Chicago.

'The Rise of Skywalker' opens nationwide on December 20th.

Lucasfilm president Kathleen Kennedy also reiterated that "Episode IX" will close out the newest trilogy and the 9-film Skywalker saga that began in 1977.

The voice of Mark Hamill's Luke Skywalker provided the narration for the teaser, with a voice telling Daisy Ridley's Rey that the knowledge of a thousand generations has been passed on. He added that this is her fight now.

Audiences also got to see a glimpse of the return of Billy Dee Williams' Lando Calrissian and Carrie Fisher's Leia Organa.

The trailer ends with the ominous laughter of an old but familiar villain: Emperor Palpatine from the original and prequel trilogies.

Earlier Star Wars Celebrations have shown trailers or teasers from upcoming installments in the most recent trilogy that kicked off with 2015's "The Force Awakens."
