When I was a kid I was really into horror films. I watched every single horror film that came out in the 80s.

Zombies - obviously they're doing it in a much more expansive way on The Walking Dead - basically, what you used to do is you put a bunch of goo on an actor and have them shamble towards you, and it's a very effective creature.
