It has to be fake. You can clearly see that the body is from the original film and the head is just pasted on. Some people suggested that maybe that is what they are actually going to do in the film, but think about it; it's easy to do in a still image, but if you past a moving head onto a different persons body, which is also in motion, it ain't gonna work. You would be able to see the join at the neck. Besides, Jaydens appeal is his youthful good looks, whose going to want to see him with a forty year old body?? ;-)
