Take This Lollipop

Take This Lollipop is a 2011 interactive horror short film and Facebook app, written and directed by Jason Zada, which uses the Facebook Connect application to bring viewers themselves into the film, through use of pictures and messages from their own Facebook profiles. Starring actor Bill Oberst Jr. as The Facebook Stalker, the film acts to personalize and underscore the dangers inherent in posting too much personal information about oneself on the internet. The information gathered from a viewers Facebook profile by the films app is used once, and then deleted.

Showing The Facebook Stalker as a thin, creepy fellow, hunched over and typing at a computer keyboard, images provided from the accessed Facebook account begin to appear as the stalker types at his keyboard, and appears to search for the specific Facebook user who had granted access. The Stalker becomes more and more agitated as he scrolls through the discovered information, until he locates the home of the user, pulls up Google Maps, and finds directions to the users home from geographic data contained in his or her profile. With the users profile picture taped to its dashboard, the stalker is then seen driving in his car to the users location, apparently to perform mayhem.At the end of the film, a screen appears with an image of a red lollipop containing a razor blade. Below the image is the viewers Facebook screenname and the name of the stalkers next victim as gleaned from the viewers own profile. ........
