There’s a lot of zombie talk lately, specifically the Austin zombie sign scandal, and the Sundance accepted Dead Snow. The funny thing is that these two stories are in direct opposition of each other. Dead Snow takes place in a winter climate, with Nazi zombies attacking a group of vacationers. If you’re up to date on your zombie knowledge, you’ll know that this is completely unfeasible. Since zombies are literally the walking dead, they have no body heat. They would actually freeze and stay that way in the winter climate of the film. That’s where the Austin “hackers” got it right. “Run for cold climates” was one of the messages displayed on the sign. (Of course everyone knows you can’t just run for a herd of zombies.)
One question has been nagging at me lately though. Are all zombies equal in strength? Technically the flesh and muscle on a zombies bones are not crucial to it’s mobility or function, so does it hold no merit to it’s strength? If not, than would that mean every zombie was just as strong as it’s undead brothers and sisters? Perhaps, but I have a feeling this is not what civil rights leaders had hoped for.

Adam,
Since strength is directly correlated to muscle mass, and since human bodies (both living and dead) do not all have equal muscle mass, then all zombies would not have the same strength.
In the Zombie Survival Guide, Max Brooks mentions also that muscle naturally tears each time it is used, and then regenerates. So, between difference in actual muscle, states of decay*, and length of time/amount of motion a zombie has experienced, the actual strength of a zombie is definitely variable.
In fact, one might even go as far as theorize that a zombie that was a previous olympic weight lifter could in be much weaker than a 70-year-old grandma zombie, given that the grandma was a fresh conversion, and the weight-lifter has been zombified and active for a period of time (and thus has had broken limbs and extensive muscle usage and exposure to the elements).
I hope this helps.
*Since bacteria and microbes that cause decay on corpses are not found on zombies (all living things flee from zombies, naturally) what decays a zombie is exposure to weather, sunlight, changes in temperature, activity, and collisions with other objects. Since zombies do not have sophisticated motor skill, nor do they ever remain inactive, a zombie would naturally suffer from extensive self-inflicted incidental damage.
Ben, we are in agreement, but due to separate points. My point was that muscle mass doesn’t even matter to a zombie, regardless of whether or not you have more or less due to natural or paranormal causes. I guess since a zombie would be just as functional with everything but it’s brain, would a smarter zombie be stronger than a dumb zombie?
Regardless, you should click this.
I wrote my last response thinking that the movie was about virus/biological zombies, not otherwise paranormal activities (witchcraft, voodoo, radiation, Return of the Night of the Living Dead-type gass, Led Zepplin reunion tours, etc). I totally agree with you.
