One of my favorite movies is Alive. It's about that sports team from (I think it's) Brazil whose airplane crashes in the Andes. They run out of food and have to resort to cannibalism to survive. Anyway, one day, I rented this movie called Flight of the Living Dead. It wasn't all that, but it was okay. The good thing is that it sparked an idea en mi loco cabeza.
I thought, what if there was a zombie outbreak on land at the same time a group of people is stranded in the middle of a mountain range? They would have the same moral dilemma about cannibalism as in Alive, but would have the added question of their humanity vs the zombie's humanity. What makes us any better than them? The perfect name for this new story was of course, Alive Again.
I love the moral dilemmas that come along with having monsters that we can each become. More on this subject can be found in the books: The Undead and Philosophy edited by Richard Greene and K. Silem Mohammad, and Gospel of the Living Dead by Kim Paffenroth. As they said in George Romero's Night of the Living Dead, "We're them and they're us."
