If a lead character with criminal past wasn't enough of an indication, co-star Riz Ahmed says "Rogue One: A Star Wars Story" is edgier than previous installments of the blockbuster sci-fi franchise.

“The film is about complex characters and loyalties and murky pasts," the actor, who plays cargo pilot Bodhi Rook, told TheWrap. "The film is a little edgier, with people making these huge compromises. History isn’t always clear.”

As previously revealed, Rook's abrasive nature and tense or volatile attitude doesn't stop the team from leaning on his skill as a pilot. Ahmed also hints that, although Rook initially treats his flying as just a job he's very proficient at, the film's events may light a new fire in him due to the extraordinary circumstances.

The first "Star Wars" standalone film, "Rogue One" follows group of unlikely heroes that band together on a mission to steal the plans to the Death Star, the Empire’s ultimate weapon of destruction. “I don’t think it will disappoint,” Ahmed said.

Directed by Gareth Edwards, the film also stars Felicity Jones, Diego Luna, Ben Mendelsohn, Donnie Yen, Mads Mikkelsen, Alan Tudyk, Jiang Wen and Forest Whitaker.

"Rogue One: A Star Wars Story" opens Dec. 16.
