Why do all of these promo shots look like they've been shot in sunlight?
Because they're trying to compensate for Craig's ageing? That's one possible reason why he looks so mannequin-like in most of these posters and prom shots.
While I surmised this was the intention behind it too, I don't know why they kept him looking ghostly white if that was the case. They could still have kept him young without looking sick. And in my personal opinion, he's aging just fine.
