I did a review of this movie recently. I was a little annoyed by the extent to which they go with the whole "the police think I'm a hippie so nobody listens to me so it's up to me to save the day while the pigs think that I'm really the killer and they try to pin the murders on me!" thing, but I guess that appealed more to the anti-establishment crowd 30+ years ago. Also, I think you might be wrong about the movie ripping off
Dawn of the Dead, as it was apparently filemd 4 years prior to the Romero classic. Now, a European rip-off of
Night of the Living Dead I could agree with.
The crazy contact lenses that look like cartoon "KABOOM!" explosion graphics were probably the high point for me, coupled with the seemingly unstoppable cemetary ghouls, and the creepy diaper wearing, beard-o zombies in the hospital morgue. I also loved the random streaker in the beginning. What a perfect way to confuse your audience with harmless nudity before trying to scare the crap out of 'em! The posters of the movie's alternate title,
The Living Dead at Manchester Morgue, are probably some of the creepiest horror movie posters I've ever seen...
... and of course I can't find an image of the poster I'm thinking of online now.
But if you're really looking for pointless nudity and the living dead, check out
Zombie Lake if you haven't already Indy. Depending on your stance on pointless full frontal nudity, you'll either be pleasantly surprised or annoyed all to Hell.
