I think the metal thing on Malak's face might be removeable, so you can see him without his lower jaw like in the game's cutscene. The crappy thing though, is that it looks like Malak is too short. He was kind of a tall, imposing, Vader-ish character in the game.
The thing with KOTOR, is that it was meant to give you a total SW experience without ******* with the continuity. That's why you have all the elements of SW without actually having the same characters you're used to. That's also why it worked so well.
