Michelle Trachtenberg Talks About Almost Being Cast as Bella

According to Celebuzz, Michelle Trachtenberg told Us Weekly that she had the part of Bella, but her schedule didn’t allow for it:

We can never imagine Twilight without our girl Kristen Stewart, but Michelle Trachtenberg told Us Weekly the role was almost hers but “schedules never worked out.” 

“There was definitely interest here and there because there’s only so few pale girls in Hollywood,” she explained. “I’ve known [director] Catherine Hardwicke since the movie Thirteen. I was actually supposed to star in that, but I was on Buffy at the time.”
