The lighting in the two films especially the dramatic bits in the court scenes, are totally different. Plus I'm sure the makeup wasn't quite consistent.I debated with myself over whether to submit this one because it actually gets less noticeable the more you look at it in stills, but despite the Klingon ambassador in IV and VI being the same actor in the same outfit in mostly the same makeup, if you watch them in close proximity he almost looks like a different person - like, he goes from being a slim(mer) young(er) black dude to an old fat white dude.
Alot of that is probably John Shuck himself getting older, fatter, and whiter (hey it happens), but it's actually kind of striking, and I'm not totally sure all that covers it, either (I think it might be the eyebrows).
