I watched this on VHS in 1992 after tying one on during a night out in the big city with my wife who I had just recently married. We got into an alcohol fueled fight when we got back, so she went to bed angry and I stayed up and watched Brain Dead.
Well I clearly got the better end of that deal because I ended up having the time of my life.
Who would've known at the time that this funny, gory, and completely insane bundle of pure New Zealand lunacy from Peter Jackson would eventually gift us the Lord of the Rings trilogy!
It's been nearly 30 years, but the lawnmower scene is still stitched fondly into my memory.
What a blast!
Slightly Irrelevant Afternote:
The title I remember was Dead Alive which in my view is FAR superior than Brain Dead.
