But I always thought it was unlikely in the zombie flicks that portray the fact that they do that the zombie could crawl out of a coffin and up 6 feet of dirt. Besides they seem to be motivated on a need to feed and nothing in a coffin would agitate them.
I guess filmmakers hope the same suspension of disbelief used to buy cannibal zombies will apply to a rotting body bing able to move through hundreds of pounds of dirt, yet when they are walking around, they are no match for most humans in one on one struggles.
