Check out all these production stills of the movie Daybreakers that opens January 8, 2010.  I have been following this film and by looking at the pictures, it appears that Ethan Hawke changes from a vampire to human. 

The story is about the human race becoming predominately vampires with very few humans around to supply them with blood.  If the vampires don’t get their sustenance they turn into these creepy creatures (below).

This one is not too pretty either nor is he happy.

Here is Ethan Hawke looking mighty human to me.
