On yet another anatomically innacurate hand, I am finding a whole new way to appreciate movies. Consider the logistics of costuming, makeup, wrangling and feeding 100 zombies. Consider the cost of materials for special effects makeup and general effects. Consider that most places that have the materials won't ship them until it gets warmer. Locations. Adequate toilet facilities for 100 bored zombies in a town of population 600. Somewhere there is an internet page devoted to the calculation of what is considered "adequate", and one would assume it takes into account peak catastrophe (like Taco Night at craft services) issues.
Does this sound like a fun job to you?
Would you be willing to do it for free?
