I snuk out and saw the Dawn of the Dead back when I was a Hare Krishna. I got a good chuckle seeing the HK Zombie. But couldnn't help notice the inaccurate costume. It looked like he was wearing an orange dress (not a dhotie) and also he was carrying a tambourine, which is not somethings HK's would bring with them. They actually play hand cymbals and also a 2 headed drum, which is separate.
Mike Christopher seems like a pretty cool guy. Though I don't know him personally I've talked to him online before and he always wishes me a Happy Birthday. Nice guy and he will always be my favorite zombie from Dawn of The Dead.
