Happy apocalypse again everyone!

I’ll do you one better, if their cells are incapable of dying then the individual cells can keep crawling toward you even if you scatter them to the winds with a gunshot, then you could have a situation where you inhale or ingest zombie cells and the cells could attack you from the inside like some kind of hyper-virulent infection (I think I just thought of an award winning scene for the next major zombie movie, BTW).

I think the only way to really kill a zombie is with fire, extreme cold, or acid baths, you have to kill each individual cell you see.
On a side note this post is starting to turn into the “treatment” for a really good zombie apocalypse movie.

How about we get a rocket, paint on the outside of the door "Free Brains". Once inside we close them in and shoot them into space. Maybe the sun. Not very cost effective. Boring movie.

Wasn't Will Smith in a zombie like movie where he was trying to make anti-zombie immunity/vaccination?

sort of, but they were infected with a virus that made them act zombie like, they weren't actually undead and they didn't use the visual if undead zombie cells infecting people and turning them into zombies in front of the camera, nor did he ever use acid or extreme cold to kill the zombies, so it all still works for a separate zombie movie.
