Injecting Church (spoilers)
Did anyone else get a little disturbed by this scene? It was obvious to me that they used a real cat (with the actor picking him up and injecting him with "something") right up to the part that he "dies", but the dead cat they use at the end is markedly more realistic than the dead cat they use when church dies earlier in the film.
It's shockingly realistic actually, in my mind unfortunately undone in the following scene in which a 2-year-old nearly overpowers an adult. For me the cat-kill was the most memorable part of the film.
