National Geographic Channel presents its history of Halloween in this 3:12 video.  It’s a bit dramatic but well produced.  As an alternative, you can buy the “Ghosts of History” video to project ghostly images of people in “colonial clothing” on a scrim.  I’m not sure the colonial period was the scariest for America–how about the attack on Pearl Harbor or the Cuban Missile Crisis?
