3. Kristen Stewart
Kristen Stewart has a number of emotions in her locker, but she clearly chooses to reserve them for extreme situations that might somehow require them, rather than bringing them into her roles on screen. Lounging around through most of her roles with the detached air of a marijuana enthusiast, she is coolness personified, but to a destructive degree. They say it's not about what you know but who you know, so one can only suspect that Stewart must know some pretty powerful people in Hollywood. She seems to have made a career out of just looking really confused all the time, between bouts of intense anger. Quite how her casting sessions go is anyone's guess, but she's clearly doing something she doesn't on screen. It made sense to have her in Twilight because that wasn't exactly a film series that was sold on anything other than raging teen hormones but anything else after or before that is a mystery. You've got to wonder how much farther her monotone voice and lack of acting skills are going to carry her.
