Summer Glau has been chatting about the upcoming season two of The Sarah Connor Chronicles, and has revealed some of the tricks she uses in order to make her seem less human.

Summer plays Cameron Phillips, a terminator sent from the year 2027 to protect John Connor and his mother, Sarah Connor.

In order to play the part believably, Summer tries not to blink, flick her hair or display any other human like traits or habits. She admits that it is a role she plays from her head and not her heart.
