A new theatrical trailer for Star Wars: The Last Jedi debuted on Monday night during the half-time American football game.
Fireworks flashed and Stormtroopers marched onto Chicago's Soldier Field as the preview played onscreen.
Walt Disney, which owns the rights to the Star Wars franchise, used a similar tactic two years ago when the third trailer for Star Wars: The Force Awakens.
The Force Awakens reunited the cast of the 1977 first film in the "Star Wars" series, Harrison Ford, Carrie Fisher and Mark Hamill, and introduced a new generation of characters.
The film made more than US$2 billion at the global box office.
The cast for Last Jedi includes Daisy Ridley, John Boyega and Adam Driver.
The new film is scheduled for release on December 15, according to the trailer.
