Behind Glen Echo...

I just got a copy of the DVD - Behind the Mask, The Rise Of Leslie Vernon, (thanks Roger!). It's great! A "mockumentary" of some film students interviewing and following around a mass murderer in the mold of Jason/Freddy/Texas Chainsaw Massacre, etc. And it supposedly takes place right here in our own little Glen Echo, Maryland, (although it clearly wasn't shot there). The film features dozens of in-jokes and cameos and has some creepily funny scenes dealing with a film genre that's ripe for satire.
