Re: Klingons in STID--why do they look like [SPOILERS]?
The first three are different actors but are understood to be the same person, the 4th is because of a bigger budget and perhaps Starfleet spent more on ships in the alt. timeline because of Nero's attack, the 5th one makes no sense at all and the last one is because the Kahless that Kirk etc. saw was his idea of what he would have looked like, not what Kahless actually did look like.
Surely this comes under bigger budget too? It's why the Klingons were given bumpy heads in the first place.
