Adam Hart is a stunt performer, stunt coordinator and actor who doubled for Christian Bale as the character John Connor in Terminator Salvation.
Following the tests, Dr. Henry Hallson discovered one member of the group possessed an incalculably and superhumanly powerful mind. As the tests were done anonymously Henry had no way of knowing which member it was, so he tried a test using a psi wheel, when the genius refused to reveal himself, he suggested they all concentrate and let the genius remain anonymous and as such the wheel began to move, first slowly then faster and faster. For this discovery Adam killed Henry with telekinesis; however Henry had time to scrawl on the wall his name as a clue before he died. As Henry was a childhood friend of Adam, he realised just before he died, it was him who was the genius.
