IVhorseman hit the nail on the head with that one. MAJOR difference. Real zombies (if their was any *sigh*... a guy can dream) are half minded meatsacks infected by solanum, a re-animation virus. They have no power of thought whatsoever, but excell in their other senses (smell, hearing, and sight) depending on their rate of decomposition. They know living from dead, and cannot be fooled by simple tricks or traps. They can infect through bites, scratches, and human digestion of infected flesh/material. Since their bodies are pretty much dead, they never have to breath, and can feel no pain. Ridding of them permanently can be done through decapitation or brain destruction (decapitation doesn't necessarily mean instant death as the head may still be active and attack you after separation).
Movie zombies can take on some, all of, or none of the facts above. They are simply made to entertain us, and have little to no informative facts on combat with the undead... let alone survival.
If you want the facts set straight I definitely recommend Max Brooks's Zombie Survival Guide (which is where I got all the above facts).
When cities burn and armies turn to flee in diseray
The weak ones cry "tis best to fly and fight another day!"
But true heroes know deep in their marrow when they die and fall,
"Tis better to have faught and lost, than to have never faught at all!"
