Variety article reports that the producers of Fox's hit Prison Break are experimenting with some transmedia tactics similar to those that were used in the failed Majestic... but with a TV show, it seems like a reasonable way to keep fans engaged and emotionally invested.
In recent weeks, as the show worked up to Monday night's fall finale, viewers might have noticed that a cell-phone number used by character Nika Volek (Holly Valance) wasn't of the typical "555" variety. Instead, it was a working phone number, (312) 909-3529. When called by viewers, it leads to a cryptic voicemail message from Luca.Earlier in the season, producers also dropped an actual email address used by another character, LJ Burrows (Marshall Allman). Send an email to the address -- LJ@ign.com -- and you'll get a coded response back.
Apparently they've had a good deal of response from fans, some of whom even leave "in character" voice mail messages which the the creative team listen to at work. Now what would be fascinating is if a new character got introduced to the show on the basis of an idea that a fan developed through these interaction channels.
