Just finished up watching the original 1978 version of Dawn of the Dead. I watched both the regular and European version, not much different, a few scenes but most the same.
People in a mall having some fun to 70's music, oh and being attacked by Zombies. I will say having seen the 2004 version first (and a super bunch of times over and over) I was a bit disappointed in the ending of the 1978 version. It certainly left things up in the air, in a helicopter actually. Where as the 2004 remake pretty much tells you this is what happened, by watching the video the survivors were making.
An interesting fact is the the main black character Peter in the original movie was played by Ken Foree. Who again shows up in the 2004 version as a Televangelist, saying one of his lines from the original. "When there is no more room in Hell, the dead will walk the earth."
Ken Foree was also referenced in Shaun of the Dead. Shaun works at Foree Electronics.
