When in the social psychology unit, I love showing the episode "Constructing Social Reality" from the Discovering Psychology series. This is available at learner.org. Among other things, it has Jane Elliott. But in one short burst of images dealing with cults, the episode shows a stadium of people getting "mass married" by Reverend Sun Myung Moon of the Unification Church. My students are amazed and disbelieving of this as a real event. This morning, on NPR, there was a story about Moon's most recent and possibly last mass wedding.
The story and images capture the immensity of the event and are worth examining within the context of our understanding of reality and cults. The article gives some nice context and insight into the process and the group.
