Hank Azaria to Voice CG Gargamel in Smurfs?

OK, so we knew already that Neil Patrick Harris would play the live-action lead in the big-screen adaptation of Smurfs, while the little blue critters would be CG and voiced by an atrocious cast led by Katy Perry, for some reason. Now, though, EW is reporting that Hank Azaria will voice Gargamel, who I'm pretty sure is a human. So real humans and cartoon humans will be interacting? Is that necessary? Is this whole movie necessary? No, you're out of order! [EW]
