Considering that "Rogue One: A Star Wars Story" was set in the moments leading up to 1977's original "Star Wars" film, it made sense that the movie included iconic villain Darth Vader in more than just a cameo appearance. The Dark Lord of the Sith not only intimidates from afar in the film, he also shows up for a truly terrifying action sequence in a horrifically cramped corridor, killing a dozen Rebel soldiers in the process.

During an Ask Me Anything session on Reddit, director Gareth Edwards revealed what it was like directing a movie villain as threatening as Darth Vader.

“You kind of get nervous," answered Edwards. "Even though you know it’s an actor inside, once that helmet goes in, it’s DARTH! And as strange as it seems, it’s really hard to tell him what to do, no one tells DARTH what to do. So you find you have to talk with the actor and figure it all out before the helmet goes on, as once he’s in character, Darth is in charge, and if you screw up the shot, he is not that forgiving.”

Set just prior to the events of 1977’s “Star Wars,” “Rogue One” follows a ragtag group of Rebels who undertake the dangerous mission to steal the design plans for the Galactic Empire’s planet-destroying new superweapon, the Death Star.

Directed by Gareth Edwards, “Rogue One: A Star Wars Story” stars Felicity Jones, Diego Luna, Ben Mendelsohn, Donnie Yen, Mads Mikkelsen, Alan Tudyk, Riz Ahmed, Jiang Wen and Forest Whitaker. “Rogue One: A Star Wars Story” releases digitally on March 24, while the Blu-ray and DVD combination bundle will be available April 4.
