How do I make my AI turn to look at the player, but not move towards him?

I’m trying to make my AI look towards the player while talking, but I don’t know how to make the AI do this without using Lookat, which is buggy and looks strange.
I see that the Third Person Character script has a variable for stationary turn speed, but I can’t find out how to make the AI turn in place.

Lookat is the way to go, what do you mean by “buggy” ? Are you making the whole character look at player or just the head ?
