Old favourites returned in the final trailer for Star Wars: The Rise of Skywalker.
The blockbuster, directed by JJ Abrams, will bring to an end the nine-part saga that began with the original Star Wars in 1977.
The eagerly awaited trailer premiered on US TV during an NFL match on Monday night, giving fans a final glimpse of the film before its December release.
Fan favourites Luke Skywalker and Princess Leia make an appearance, with the latter's involvement coming on what would have been the late Carrie Fisher's 63rd birthday.
She was best known for playing Leia before her death in 2016 at age 60.
Abrams had previously revealed unused footage from previous films would be used to bring Fisher back for the saga's final instalment.
The two-minute trailer also stars British actress Daisy Ridley, who reprises her role as resistance fighter Rey.
She battles the evil Kylo Ren, played by Adam Driver, while John Boyega's Finn features.
"People keep telling me they know me," Ridley's Rey says in the trailer. "No one does."
Ren replies: "But I do."
Towards the end of the teaser, a mystery figure in a black billowing hood appeared, leading fans to speculate feared villain Emperor Palpatine will make a return.
The Rise of Skywalker will complete Disney's new Star Wars trilogy and is set to be one of the biggest entertainment events of the year.
The two previous instalments in the trilogy, 2015's Star Wars: The Force Awakens and 2017's The Last Jedi, grossed a combined $US3.3 billion.
The Rise of Skywalker will be released in Australian cinemas on December 19.
