Star Wars: The Force Awakens was a massive box office success, earning over $2 billion, and this week’s home release is expected to break even more records. So, the timing is perfect for Disney and Lucasfilm to promote a new film in the franchise.

This morning, the companies released a new teaser trailer for Rogue One: A Star Wars Story, and fans are already hyped. This prequel actually ties in with the earlier films, with a ragtag group of soldiers assigned to steal the plans of the Death Star, a super-sized intergalactic battle station that was heavily featured in the original movie trilogy.

Directed by Gareth Edwards (Godzilla), the movie features an all-star cast, including Felicity Jones, Donnie Yen, Diego Luna, Forest Whitaker and Mads Mikkelsen, and promises to be “a departure from the saga films but have elements that are familiar to the Star Wars universe,” according to Lucasfilm president Kathleen Kennedy. “It goes into new territory, exploring the galactic struggle from a ground-war perspective while maintaining that essential Star Wars feel that fans have come to know.”

The teaser premiered earlier today on Good Morning America before being let loose on the Internet, where millions of fans immediately began discussing it on social media. Most of the responses have been positive, with fans excited about a return to an “old-school” style—characterized by the appearances of Star Destroyers, AT-AT’s and classic stormtroopers—that is reminiscent of the original movies from the ’70s and ’80s.

The film is set to undergo a huge promotion over the next few months, which will include a heavy presence at this summer’s Star Wars Celebration in London, possible new content for the game Star Wars: Battlefront, and perhaps new toys and products that are similar to last year’s The Force Awakens line-up. Disney hasn’t revealed all its plans for Rogue One promotion yet, but we’re certain to see much more rolling out over the next few months.

Rogue One: A Star Wars Story releases in theaters on December 16th, 2016.
