I have a huuuuuuuuuuuge question regarding the "Science" of this movie (surprise, surprise). How the hell did they switch their teeth???? They explained the face, hair, and voice adequately enough. But the teeth?!?! They would have had to switch skulls for that to work! I mean at least gloss over something "dental" sounding to explain it. I really wanted to be on board with the idea but the teeth are so distracting.
