Now as some of you know in the 1st trailer of Dark of the Moon Sentinel Prime was gold, but in the movie and in the toy's he is red and black. Now after seeing the movie and the trailer again I have seen some more changes. In the trailler Sentinel look's a lot bigger and bulker and his face look's older in the trailer, but in the movie Sentinel look's a lot thiner and look's a bit less old looking and his paint job look's a lot shinery and look's like a he is a brand new bot. Does anyone know why this happen as I alway's wanting to know why the change happen? Even when I saw the movie for the 1st time I thought I saw the changes.
