They're coming!

In certain canons, if you burn a zombie and inhale the smoke, you may become a zombie yourself. If you do intend to set them on fire, make sure there's somebody you don't like (and who doesn't owe you money) downwind.

That doesn't make a lot of sense.  Fire destroys all known viruses and bacteria, how could zombieism spread from ash?

Fire doesn't spread a strong desire to feast on brains, does it?

Who says that the zombie plague has to be spread by bacteria or viruses? Perhaps it can be spread by a chemical that can become gaseous when burnt.

Or perhaps it's because not all authors totally think through their designs.

I've seen numerous movies where zombies were on fire, and I don't recall any instances of the plague spreading because of it.

Chemical?  That implies manmade.  Even manmade zombies (Biohazard/Resident Evil) were created by means of a virus.  If there's some kind of chemical that can make zombies....god save us all.

Clicky. The zombies were created from exposure to 245-Trioxin (not real), and when they tried to get rid of them by burning them in the crematorium, it caused the corpses in a nearby graveyard to turn into zombies. Since the chemical in question is entirely ficticious, it is prefectly plausible that it could spread through the air after being burnt. Excellent movie too

Haha, I loved Return.  The best scene(s) was when the chick was explaining how she'd want to die, and then when she died.  Anyway, 245-Trioxin doesn't make sense.  It brought BONES back.  WTF?  Bones have no muscles or tendons connecting them and giving them a way to move.
