A new trailer for "Rogue One: A Star Wars Story" debuted Thursday on ABC's "Good Morning America," two months before the film is set to be released in theaters. You can watch it below.

"Rogue One" takes place between the prequel and original trilogies as the Empire's hold on the galaxy continues to strengthen. A ragtag rebel militia led by Jyn Erso (Felicity Jones), are sent in to pull off a mission that could be the last chance to defeat the Emperor. Their job: steal the plans to the Death Star. Among her allies are Rebel intel officer Cassian Andor (Diego Luna), Force warrior Chirrut Imwe (Donnie Yen), and Clone War veteran Saw Gerrera (Forest Whitaker).

A new poster featuring the entire main cast was unveiled by director Gareth Edwards, who appeared on "The Star Wars Show" to discuss the film. The poster also feature Imperial forces on the tropical island of Scarif, which will be featured prominently in the new film.
