The Kuleshov Effect is a film editing method developed by a Russian filmmaker (named Kuleshov :)) back in the earlier part of the last century. It takes advantage of a mental phenomenon where viewers derive more meaning from seeing a series of pictures rather just one by itself. In writing this is the old E.M. Forster chestnut, "The king died. The queen died." Or how changing a few words takes events from "events", to a story, then a plot.
The king died. The queen died (being two events that may or may not be related).
The king died, then the queen died (being a story).
The king died, then the queen died of grief (being a plot, or how the story is shown).
Let's take a quick look at the Kuleshov Effect itself. Click on the link in the word for a wikipedia explanation and check out the youtube videos.The first video is Kuleshov's original work, and might not work well to show the phenomenon, since you're not just coming on it out of the blue, but watching it to understand how it works. Then watch the Hitchcock video about montage for forty seconds (he explains the concept behind the Kuleshov Effect well). Then jump to the 5.40 mark so you can listen to him talk about how it works while you watch "his" version of Lev Kuleshov's video.
The Kuleshov Effect is the reason prologues work, and how they can be used to "spin" a story, or influence it in one direction or the other (which sets up for post 3 on prologues, as we talk about how to do that).
