Did anyone notice that in the Crazies, the guy throwing tnt looked a lot like the obnoxious guy that Ben shoots in Night of the living Dead. I think the character's name in NOTLD was Harry? Was that a NOTLD cameo or just a look-a-like?
You also have the scientist who made the virus(the stocky, bearded russian looking guy who yells a lot) was one of the scientist, or something yelling at the newscaster on the news in Dawn of the Dead (and NotLD too, right?)and the crazy girl's Dad the main characters was running around with is Dr. Logan from Day of the Dead. Probably some more too, I'm watching this now for the first time and spotted a few. Of course they are not "cameos" but it's fun to see the same peeps from George's films.
