The videos, uploaded by IamforeverNEVERMORE, offer a different perspective than the promotional material that has been released so far.
The Following premieres January 21, 9/8c on Fox.
Despite how these are numbered there aren't videos missing in the post these are the only ones that have been updated. Based on the two videos outside of the "Scene of the Crime" footage it looks like they're trying to play this as YouTube account of one of Joe Carroll's followers. These promos remind me of the Blair Witch one Sci-Fi did years ago. Can't wait for this to air.
