Please pardon my friend Joshua there. He hasn't been paying much attention to the movie-making world lately.
I'm just messing with y'all...Josh knows his stuff. But most actors in professional films do spend 2-3 hours every day of production in hair and makeup. There's an entire team of people for that. As of now...we have two - one for special effects (wounds and scars, mostly), and one for regular makeup.
"Regular makeup," in the movie sense, means a lot. There has to be several layers of different kinds of foundation, simply to make the actor's "skin" look natural. Minute adjustments are made to make the actor more attractive, slightly older, etc. And all of it has to be done so that anyone meeting the actor in real life would not be able to tell that he even had any makeup on at all. It's a tough job, but worth it if your sunburn or acne will be hidden from the high-def camera.
My friend once joked at calling his movies "No-Budget Productions." It's true for us, too. For right now, all we can do is grab one or two layers of normal foundation (none of the fancy stuff they use in movies), and a touch of eyeliner. We use nose putty instead of latex, even. We work with what we've got.
Thanks to digital editing, much of the hard work that goes into making an actor look like someone else can be done via computer. However, Josh is usually the first one to say this: "If you can do it for real, do it for real." Always full of good advice.
So that's what we're going for: doing as much of it for real as we can.
