What's the easiest way to turn a human into an alien, is it with the ears or the nose?

We have different categories for the aliens. We have the straight humans, and then we have what we know as the mild humanoids, and that usually means maybe just a little something on the nose.

Then we get into what we call a medium humanoid, and that would be possibly a forehead with maybe the nose attached to it.

A partial alien would be the full face with hair and a wig, and then I've got the full alien, which is the entire head, which is bald and no hair on it at all. And it just depends on what the producers decide on once we get the script. They might tell me, 'Ah, go ahead, make him a full alien.'
