Oh, yeah, for the SE, the original Dewback in the background was removed and instead two obviously CG ones were added. I tried rontoscoping in the GOUT one but the difference in quality was too big, so I reconstructed the original one in HD using a production photo and I had to track the motion of the camera frame by frame. And also, about two seconds of that shot were cut off at the beginning of it, so I had to deal with that too by several times repeating the few frames before the stormtrooper moves.

Thanks, it was a lot less simple than it looks though...

You're not wrong :)
