And by afraid, we mean like how people are afraid of God, or afraid of being happy...
According to our big, little-sister Fame Crawler, Hayden Christensen:
Christensen was nervous as a kitten while filming "Awake" with the mom-to be, "I remember that day. I was just so nervous. Really nervous! Running around with a light sabre is really pretend and you know that in the back of your mind, but when you are put in a situation where the scene you are doing becomes so real, it is terrifying!"
