Director rewrites

So I'm trying to read the shooting script as I watch the film again. Man is it different. I had always read that Director Otto Valkenberg was tough to get along with and maybe the fights he supposedly had with Sid account for the many script changes. Doesn't look to me like he followed Strassen's script at all. There's a few notes in her about Zombies feasting on the flesh of rabbits, but I don't remember seeing that in the film anywhere.
