Hayden Christensen & Diego Luna Discuss Their Worst Nightmare, 'Star Wars' Lightsaber Battles, Why Hayden Returned, Super Secret Auditions & More in 'Variety' Actors on Actors Interview

Diego, on his worst nightmare:

LUNA: “If I have to think about the worst nightmares of my life, it really…”

CHRISTENSEN: “…involves Darth Vader?” [Laughs]

LUNA: “I remember waiting two, three months for my Darth Vader case when I was, like, eight, nine years old. You had to go to the toy store and say, ‘I want this’ and order it. I used that until I was a teenager, until my friend said, ‘That’s not cool anymore. Can you just bring a backpack?’”
