Disney+ dropped the official, full-length trailer for the upcoming Lucasfilm series "Andor" on Monday.

In the "Star Wars" prequel series, Diego Luna reprises his "Rogue One" role as the titular Rebel spy Cassian Andor. The trailer indicates that the series will delve into the past Andor hinted at in that film -- that his career working against the Galactic Empire began when he was just a child.

"To steal from the Empire, you just walk in like you belong. They're so proud of themselves," he says as he's shown infiltrating Imperial bases both as a child and as an adult. "They can't imagine that someone like me would ever get inside their house."

The trailer also hints that "Andor" will be a galaxy-spanning adventure, from the Galactic Republic's capital planet Coruscant, to dogfights in space and skirmishes with Stormtroopers in the streets of various worlds.

"This is what revolution looks like," Adria Arjona's mysterious -- and as of now unnamed -- character tells Andor.

"Witness the beginning of Rebellion," a title card teases.

"Andor" -- also starring Genevieve O'Reilly, Stellan Skarsgård, Forest Whitaker, Fiona Shaw, Alan Tudyk, and others -- kicks off Sept. 21 with a three-episode premiere on Disney+.

Lucasfilm is owned by Disney, the parent company of ABC News and "Good Morning America."
